N-烯丙基-N′-(对苯磺酸钠)硫脲在Sr~(2+)的鉴定中对干扰离子的掩蔽作用

The sheltering function of N-allyl-N′-(sodium pWT4HZ-phenyl-sulfonate) thiourea in the identificatio

  • 摘要: 以实验为基础 ,提出了用玫瑰红酸钠试法鉴定 Sr2 +时 ,用 N-烯丙基 -N′-(对苯磺酸钠 )硫脲同时掩蔽 Ag+、Au3 +、Hg2 +三种离子对鉴定 Sr2 +离子的干扰的简便有效的方法 .

     

    Abstract: Based on exeperiments,the N-allyl-N′-(sodium p-phenyl-sulfonate)thiourea is used foreliminating the interference of Ag +?Au 3+?Hg 2+in the identification of Sr 2+ using Rhodizonic acid disodium salt.In comparison to the traditional method,this method is easy,simple and effeetive.
