ABSTRACT

The complexation of gallium with 2-hydroxy-5-T-butylphenol-4’-methoxy-azobenzene (HR) has been studied by atomic absorption and spectrophotometric methods. The optimal conditions for the formation and extraction of the complex were found. The maximum light absorption of the complex in n-butanol is in the range of 450 - 470 nm. The molar absorption coefficient is (3.3 - 4.2)104. The stability constant of the gallium coordination compound in n-butanol is βl = 4.21010. The developed technique allows to determine the gallium content within n × 101 - n × 104%. The selective and sensitive technique for the extraction-atomic absorption determination of gallium in soils has been developed.
