Ion Exchange Adsorption Kinetics of Miglitol by D001 Resins ()
ABSTRACT
In order to explore internal factors for adsorption kinetic effect of miglitol by
D001 resin, a batch adsorption operation for miglitol kinetic adsorption at
different concentrations, temperatures and vibrating rates was investigated in
oscillator (SHZ-A), respectively. The different kinetic mathematical model,
Webber-Morris kinetic equation, film diffusion coefficient equation and kinetic
boundary model were all applied to discuss the adsorption process. The
results showed that Type 1 pseudo-second order kinetic equation can be all
used to describe miglitol adsorbed by D001 resin at different concentrations,
temperatures and vibrating rates. Moreover, the total activation energy (Ea)
can be calculated and its value is 9.7 kJ/mol, and then calculated values of the
process film diffusion coefficient and pore diffusion coefficient, it may be inferred
from these gotten values that the ion exchange process is all mainly
controlled by film diffusion. Therefore, the results also suggest that the external
adsorption factors such as solute concentration, temperature and vibrating
rate for effect of mass transfer diffusion process control of miglitol onto D001
resin are relatively weak.
