The sample of PdCl2 was dissolved in NH4OH. The impurities including Pb, Sb, Bi, As, Sn, Fe, Zr,Cr,Be,Ti et al in PdCl2 were determined by ICP-AES after coprecipitation with Y(OH)3. The determination range of the impurities are in the range from 0. 0002% to 0. 01%. The standard recoveries are from 84% to 114% with the relative standard derivation of 2. 2%-7. 4%. The method was accurate,simple.
