摘要
在用玫瑰红酸钠试法鉴定Ba2+时,Hg2+和Au3+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Hg2+和Au3+的干扰,与传统消除干扰的方法相比,具有条件易控制,操作简便,掩蔽彻底等优点。
Based on exeperiments, a method was described for the eliminating the interference of Gold and mercury with the N-allyl-N′-（sodium-p-benzenesulfonate） thiourea in the indentification of barium using Rhodizonic acid sodium salt？. 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.
