Description
The behaviour of microamount about 30 elements and macroamount of cadmium in extractive and extraction-chromotographic coefficients of distribution of these elements at concentration of HBr from 1 to 7 M have been determined. The method of isomolar series was used to determing the composition of sorbted complex of cadmium in present system at concentration of HBr 1 and 6 M. It was found that at concentration of HBr 6 M cadmium is sorbed in the form of dibasic acid H2CdBr4 and from 1 M - HBr in the form of monobasic acid HCdBr3. The influence of complex composition on sorbent capacity has been studied. The method of radiochemical and neutron-activation analysis of high purity cadmium allowing to determing more than 30 impurity elements with the limits of determination 10-4 - 1-8 mass.% has been carried out.
