Determination of Palladium in Fresh and Spent Pd/C Catalyst by ICP-AES

Fang Haiyan

Abstract

The content of Pd was determined through(1) wet digestion with HNO3-HClO4or ignition at 700℃ to remove carbon,(2) dissolution of the residues by aqua regia and(3) determination of palladium by ICP-AES.Pretreatment of sample,accuracy and precision of the method were discussed.The additional standard recovery is 99%~101%,RSD 1%.The method is simple,accurate and fast.
