摘　　要：探讨了汽车催化剂的微波消解过程中酸的用量及种类,以及可能存在的残渣物是否影响测定的问题.经过对消解程序的优化以及酸比例的调节,建立了一种可大大降低HF用量,就能得到清亮消解液的新方法;实验证明不加HF消解的1次残渣物,以及残渣物2次消解后的残留物中,基本不含有铂、钯、铑等贵金属元素.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.
