| Abstract: | Trace amount of Pb, Cd, Co, Ni, Fe and Cu in highly pure RE oxide is determined by flame AAS after coprecipitation with ammonium pyrrolidinedithiocarboxylic acid (APDC) as coprecipitator. Conditions of an optimal coprecipitation procedure were elaborated. This method has been successfully applied to determine trace Pb, Cd, Co, Ni, Fe and Cu in highly pure La_2O_3, Y_2O_3. |
