A New Method of Digest Automotive-Catalyst by Micro-wave Digestion

ZHOU Hui1,REN Pan-pan2,GAO Yun-chuan2,SHAO Min 1, ZHOU Hai-ming 1,SUN Ming-xing1(1.Shanghai Entry-Exit Inspection and Quarantine Bureau,Shanghai 200135,China; 2.Shanghai Normal University,Shanghai 200234,China)  
The variety and amount of acid factors during Micro-wave digestion,as well as whether the residues affect the determination were discussed.After optimization of digestion procedure and the acid ratio,the amount of HF can be greatly reduced,at mean time,it still gets a clear digestion solution.Without add HF,digestion residues and residues after the second digestion residues,which were proved seldom containing platinum,palladium,rhodium and other noble metal elements.
