A separation procedure of trace platinum from large amount of mercury and other interference elements is described and it has been successfully applied to the identification of new isotope 202Pt. After irradiation the HgO target was dissolved in concentrated HC1 solution. The thallium fraction was removed by the solvent extraction with ether. In the aqueous phase after extraction the radioisotope of platinum produced by irradiation was precipitated as (NH4)2PtCl6 by adding saturated solution of NH4Cl in the presence of H2PtCl6·6H2O as stable carrier. The decontamination factors from mercury
gold and thallium and the recovery of platinum in the process of separation are satisfactory.
