Abstract

For the first time, a new approach was given to solve the problem of separation of analytes (Se, Te) from matrix elements Fe, Ni, Ti, Cr, Mo, Co, Ta, W. Matrix elements provide an interfering effect on the results of Se and Te determination employing the ICP-AES analysis. It was found that required deposition conditions of macroamounts Fe, Ni, Cr, Co should meet 5 g Na2C2O4, 2 g NaF and 15 cm3 HF. However, in the analyzed solution there are a large number of Ti, Ta, Mo, W.
