摘要
在用双硫腙试法鉴定锌时，银、铂和钯将产生干扰。试验发现，用N-烯丙基-N′-（对苯磺酸钠）硫脲可掩蔽银，铂和钯对锌的干扰。与传统消除干扰的方法相比，具有条件容易控制，操作简便，掩蔽彻底等优点。
Based on exeperiments, a method was described for the eliminating the interference of Silver,Platinum and Palladium with the N-allyl-N＇-（sodium-p-benzenesulfo nate）thiourea in the indentifica- tion of Zinc using Dithizone. Comparing with the traditional method, the new method has some advantages. It is simple and can eliminate the interference completely. Moreover the experimental conditions are easy to control.
