摘要
通过发现钯（Ⅱ）在磷酸介质中能抑制二安替比林对氯苯基甲烷（ＤＡｐＣＭ）与钒（Ⅴ）的显色反应，研究了反应的条件和动力学参数，建立了测定微量钯（Ⅱ）的新方法。本法线性范围为８０～４８０μｇ／Ｌ，检测限为８０μｇ／Ｌ。用于冶金产品和钯催化剂中钯的测定，结果满意。
It was found that palladium(Ⅱ),in the medium of phosphoric acid,can inhibit the color development reaction of DApCM and vanadium(Ⅴ).According to the findings,the reaction conditions and kinetic parameters were studied and a new method of determining micro palladium(Ⅱ) by inhibitory kinetic spectrophotometry was established.The lined range of the determination by this method was 80～480μg/L while detection limits was 80μg/L.The results of determining palladium(Ⅱ) in metallurgical products and catalyst were satisfactory.
