The interaction of germanium with 2-hydroxy-5-T-butylphenol-4-methoxy-azobenzene (HR) was studied. Optimum values of pH of solution are 3.5÷4.0. Maximum light absorbance of the complex in n-butanol is in the range of 470÷480 nm. Chloroform, dichloroethane, carbon tetrachloride, benzene, toluene, xylene, hexane and n-butanol were tested for extraction of the complex. The most effective extractant was found to be n-butanol used in further studies. Absorption spectrum indicates the formation of one complex.  Ratio of components in the complex under optimum conditions were found by method of equilibrium shift and straight-line method of Asmus, they are equal to Ge:HR = 1:2. Selectivity of extraction-atomic absorption determination of germanium was studied by using HR. Molar absorption coefficient equals to (4.0±4.2)·104. Beer’s law was observed at concentrations of germanium 1÷10 mkg/ml. Stability constant of germanium in n-butanol was found to be βк=3.4·106. Calibration curve was linear at concentrations of germanium 1÷10 mkg/ml. Selective and sensitive techniques of extraction-atomic absorption determination of germanium in different regions were developed.Downloads
