The Physics of the Phenomena of Electrical Induced Elements Separation in Solution of Salts in Liquid Polar Dielectric

In the work [1] is shown the possibility of the use the phenomena of the electrical-induced selective drift of cationic aquacomplexes in the water solution of the salts for creating of the new, non-electrode, power-saving technology of the solution enrichment by desired element. The development of the naturally-scientific basis of this technology has showed that inertial properties of formed in the solution over-molecular structural units—clusters depends from that’s dimensions. Dimensions of these clusters are in limits from scores of angstrom to fractions of micron, at the same time liquid mediums are the base of functioning both biological and technological systems. Thus, water solution of salt contains nanoparticles and biological and many technological systems are functioning with the assistance of nanoparticles. For example, the ordinary blood circulatory system or many of chemical processing. The casual or intentional action of aperiodic electric field on systems containing salts solutions produces some positive or negative effects. This work shows new approach for theoretical describing of salts solution in dielectric liquids and contains some data on the realized experiments.


Condition of the Problem
At dissolution occurs complex formation therefore is formed supermolecular structure-in water solutions of hydrated aquacomplexes.Aquacomplex may be considered as nanoparticle, formed from central ion and molecules of water.
At action of the external periodic electric field the solvated ions-clusters are drifting [1].The oriented drift of the polarized solvated ions allows organizing the technological process of element enrichment of water solutions of salts [2].Experimental researches have shown, that it not the sole appendix of the found out phenomenon (effect).In particular, the solutions of salts of metals in the polar, liquid dielectrics (water, spirits, ketones) show interesting properties at action of the magnetic fields.
As show theoretical and experimental researches, the size of cluster is the quantity determining the majority of physical and technological properties of solutions.Nowa-days, two approaches were developed for definition of properties of solutions.The opportunity of use of the plasma concept of a condition of solutions of electrolytes is noted in the works of M. M. Baldanov [3].The second approach assumes the modeling of processes of solvation on the basis of the incorporated quantum-classical theory of the functional of density [4].
Both in that, and in other case, for the obvious reasons, properties of solutions are defined mainly by energy of multiparty interactions of ions in the dielectric medium.And it uniquely assumes attraction of such individual characteristics, experimental definition of which is impossible (a condition of an electroneutrality), are probable only theoretical estimations, or semiempirical processing of an experimental material on the basis of some plausible, but arbitrary assumptions.
The validity of the assumptions can be certain experimentally, for example, at comparison of observable and theoretical values of any parameter which value directly depends on the solution characteristic of the defined within the limits of this or that approach.Such works have been begun in 30th years of the last century [5].
In the works [3,4] were received the radiuses values of the solvated ions, which compound units of angstroms.Use of such values at a theoretical explanation of the found out phenomenon (effect) of the selective drift of solvated cations under action of an asymmetric electric field [1] leads to estimated values of frequencies of the field (about 100 megahertz) at which it is necessary to expect display of the effect.Nevertheless, the phenomenon takes place at the frequencies which are not exceeding units of kilohertz, and at the certain concentration of salt in water-tens of hertz.Besides there are the experimental data specifying that clusters represent submicron formations [6].
In the work the solution is shown as quasi-neutral system of polarized charges which interacting with external electric field and among themselves.Consideration is spent with the purpose of definition of the geometrical sizes solvated ions-clusters and general characteristics of process of influence on the solution of an external electromagnetic field.Results will allow defining opportunities of various appendices of the found out phenomenon (effect).

The Self-Consistent Field in the Solution of Salt in the Liquid Polar Dielectric
Let' consider, that each cation (anion) causes the polarization of surrounded solvent (water): the "atmosphere" is forming around each cation (anion) with abundance of polarized molecules of the water.This "atmosphere" is shielding cation's (anion's) field.The generalized electronic shell of each polarized molecules of water is deformed concerning unperturbed configuration, when full spin of the molecule is a zero.The perturbation is caused by the action of the cation's (anion's) electric field.The deformation of the shell is cause that the part of nucleus' charge or electrons in the water's molecule will be uncompensated.This uncompensated part of a charge represents a polarizing charge of a molecule of water in a non-uniform electric field of the charged particle-cation (anion).According to representation about the self-coordinated field [7] there is such distribution of an electric field in system of the cooperating charged particles which creates the distribution of particles exciting a field.Salt solution is possible to consider as system of cooperating cations, anions, it is positive and negatively polarized molecules of water.For a finding of the self-coordinated field we shall use Poisson equation: and Boltzman distribution: where n k -concentration of particles with charging number Z k in a point with potential .For electrons, for example, Z = -1.But in a solution are not present free electrons.For cations Z = m, and for anions Z = -m, where mvalency of metal which salt is dissolved.n k in distribution (2) is a concentration of particles with charging number Z k in a point with the zero potential, equal to average concentration of these particles on all volume of a solution.
Further an index "i" we shall designate cations, an index "a" -anions, "p + "-polarized and being around of anions molecules of water, "p -"-molecules of water around cations.
Average concentration n k satisfies to a condition of quasi-neutrality: which show the fact, that the solution as a whole (from outside) is neutral.Also following conditions take place: In which it is considered, that charging numbers of cation and anion are equal on absolute value, but opposite, and charging numbers of the polarized molecules of water are determined by around of what they associated: around anions , and around cations 0 Also following connections take place: where N a -number of molecules of water, associated around of one anion; N i -number of molecules of water, associated around of one cation; Z-valency of metal, which salt is dissolved; n m -concentration of molecules of salt in a solution, if to consider they are not dissociated.
Volume charge thus, where e-the module of a charge of electron (in system SI 1.6•10 -19 C).The correlation ( 7) is very similar to expression (5) with that essential difference, which in it there is a value of concentration of particles in that point in which the potential of the self-coordinated field is de- (2) termined.
Equation of Poisson will copy in the form of: Using series expansion and considering connections ( 4) and ( 6), it is possible to receive function: Even if takes place no more, than secondary hydration, in hydrate shell it will be concentrated more than 10 molecules of water.Therefore it is possible to consider, that 2 1 i N  and 2 1 a N  . In view of this, equation of Poisson will become: The decision (10) for spherical symmetric distribution of potential (cation or anion) looks like: where constant of insulation is: The inverse value 1 l   refers to as length of insulation and it is possible to consider, that its value defines radius of solvation sphere within the limits of which the polarized molecules of water are built.They also insulate a field of cation (anion).Thus, value of cluster radius (solvated cation or anion) can be estimated, using:

The Characteristic Values of Frequencies of Excitation of Effect of Oriented Drift of the Solvated Ions
The own frequency of solvated ion (cluster) can be expressed of following equation: , where items correspond of frequencies of excitation of electron shells (e), oscillation an ion and solvated groups (k) and rotations solvated groups concerning an ion (r).It is supposed, that excitation of electronic shells or oscillation of ion and solvated groups can be initiated only after deformation solvated shell (screen), which inhibits influence of an electric field.Deformations (rotation solvated groups concerning an ion) correspond to item r  .
Frequencies of transition of oscillatory motions in rotary are defined by equation: where h-Planck's constant, I-the moment of inertia of system of the connected particles.The given equation is valid if cluster it is possible to consider as linear system of two rigidly connected particles (an ion and solvated shell), and oscillatory movement of any of particles causes rotation of cluster as the whole.These frequencies in conditions of the achievement of relative mobility of clusters, which is required for activation of process of the selective drift under influence of field, is possible to considered as the minimum frequencies of own free movements clusters.Broader range of frequencies of own motions of clusters, which is connected with free rotaryonward motions, can be presented in the form of set of the frequencies of the allowed quantum levels of free rotation by analogy to a spherical top (all of its three principal of the moment of inertia are equal): and frequencies of onward moving: where J-quantum number, n x,y,z -the projections of the vector of the rotation to coordinate axes, d-the size of cluster, μ-the brought weight of cluster.The frequency of onward moving is meant frequency of rotation of all clusters (an ion together with the solvated shell) as the whole when sets of all three main directions of the fluctuations will be transformed in each other If in Formulae (15)-( 16) the form of cluster take as spherical-"zero" approach, it is possible to consider, The number of the molecules of water (the solvated groups) in the cluster, having radius r cl , is g, d = 2r cl , , where r, V-radius and volume of the solvated groups, respectively.Thus , where K r -the factor equal to the relation of the moment of inertia, corresponding rotation solvated shell around of an ion, to average of value of the projection of the oscillatory moment on the axis of rotation.This factor characterizes intensity of the Carioles interactions (the analogy to Carioles forces in the classical mechanics).It have value 0.4 for the rotation the solvated shell around cation (anion) and 1.4-for the rotation around axis, passing regarding to surface cluster.As the weight of the solvated shell considerably surpasses weight of the ion, positions of the centre of gravity (the center of inertia) and the ion practically coincide.The values of the frequencies received in the Formulae (14)-( 16) for J = 1 (the minimal values), correspond to a case when only one aquacomplex is formed, and allow to estimate only values of the frequencies which should be expected in the experiments.
As follows from the ratio (13), the value of dimension of the cluster is inversely to a square root from value of concentration of salt in water.Values of the frequencies are inversely to the value of the moment of inertia of the cluster.The moment of inertia is proportional to the equivalent mass of the cluster, that is the quantity of molecules of water in the solvated shell   n -an amount of the molecule nit of the me, i n -for amount ion ditto, it is possible to expect that: pote tial becomes too small on distances, smaller distances between most close located ions [1].Values of frequencies, corresponding to different components of the rotary-onward motion of cationic aquacomplexes, and values of the frequencies, corresponding to the turning of the oscillatory motion in rotary, are in limits from several hundreds Hertz to several loHertz.If the solution is considered as quasi-neutral system of polarized charges which interacting with external electric field and among them, frequencies of oscillations are much less (no more than 100 Hertz).
water in u volu n in the Solution the aquation shell of aquacomplexes are displaced.As a result there is a division of the aquacomplexes, displaced to a greater or lesser extent.Polarized charges of the divided aquacomplexes differ, at least, on absolute value.Thus, there is a division of charges and electrostatic forces in volume of a solution.Electrostatic forces should lead to excitation of own electrostatic fluctuations in volume on the average neutral (in an enough great volumes or for enough greater time intervals) a solution.
Let as a result of division of the polarized aquacom exes in a solution there is a polarized charge q.Thus q  divP (1 0      P E-a vector of polarization;  -a dielectric susceptibility of a solution; 0  -an electric constant of vacuum; E-a vector of intensity of the electric field acting on a solution.We shall remind that it is a question of solutions of salts of metals in polar dielectric liquids.Thus where  -factor of polarizab cluster; ility of the solvated ion--average number of clusters in unit of vol-ume of a solution, and , where n m -number of dissociating molecules of salt in unit of volume of a solution.
The polarized charge of one cluster n   p q n  will be defined, thus, by expression: The According to the law of preservation of a charge where j-density of a current.by the polarized aquacomplexes.Then Thus the current is carried where v-speed of the aquacompl The equation of movement polarized a exes, carrying a current.quacomplex, having weight m, will enter the name in the form of Differentiating the Equatio stituting (21) in (20), we shall receive ns (20) and ( 21) and sub- Substituting in (23) expression for t   v , received of (22), a , we s nd considering, that 4π hall receive The received equation describes fluctuatio simple harmonious n with circular frequency 2 8π m n p If the solution is placed between the two flat electrodes, distance between which is not great, consideration of process can be spent in one-dimensional geometry.We shall designate through x E absolute value of intensity of the electric field acting on a solution.Then where ∆-thickness of a layer of a solution between the potential and earthed flat electrodes.Thus, the density of a volumetric polarized charge in a solution will change with circular frequency 0

Electromagnetic Wave Action on t
As well as in plasma, any separation of charges in a n of salt in l of density of a charge.On the average for many periods of fluctuations the solution behaves as quasi-neutral medium.Separation of polarizing charges is possible only on temporary intervals, smaller in comparison with temporary scale of separation of charges Value of this frequency coincides with value the Longmuir frequencies of plasma.
In our case the analogue of Longmuir frequencies is frequency of fluctuations of t e of a solution  0 .
The dielectric constant of plasma is defined by the ratio:

Conclusions
The solvation proce uid, polar dielectric opment of essentially new technologies and techniques.The conditions providing use of process mass transfer for the decision of various applied problems, first of all are defined by the sizes of solvated ions (clusters).
In particular, action of periodic electric fields with various combinations of frequency, intensity an ude of amplitudes of intensity in half-cycles on solutions of salts in polar dielectrics causes excitation of rotary-forward motion solvated ions (clusters) and, hence, mass transfer.
