摘要
基于在１００℃醋酸盐缓冲溶液中，Ｐｄ（Ⅱ）对孔雀绿氧化次磷酸钠有显著的催化作用，且该作用过程能被单扫描示波极谱跟踪这一实验事实，建立了一个动力学分析钯的新方法，方法的灵敏度和线性范围分别为０．１和０．２５～１１μｇ／ＬＰｄ，已用于催化剂中痕量钯的分析．
Experimental results show that Pd(Ⅱ)catalyses noticeably the decoloration reaction of malachite green(MG)by hypophosphate in acetate buffer solution and the reaction could be detected by single sweep oscillopolarograph,which could be the basis of establishing a new kinetic method for analysis of palladium,with a detection limit and amenable range being 0.1 and 0.25～11mgPd/L,respectively.This method has been applied to the determination of palladium in catalysts,and satisfactory results obtained.
