N—烯丙基—N′—(对苯磺酸钠)硫脲在锑的鉴定中对干扰离子的掩蔽作用

The Sheltering Function of N-ALLYL-N′-(sodium p- phenyl-sulfonate)Thiourea in the Identification of Sb

本文以实验为基础，提出了用罗丹明Ｂ试法鉴定Ｓｂ（Ｖ）时，用Ｎ—烯丙基—Ｎ′—（对苯磺酸钠）硫脲同时掩蔽Ｈｇ２＋、Ｂｉ３＋、Ｆｅ３＋、Ａｕ３＋四种离子对鉴定Ｓｂ（Ｖ）的干扰的简便有效的方法。

Based on exeperiments,the N-allyl-N′-(sodium p-phenyl-sulfonate) thiourea is used for eliminating the interference of Hg 2+ 、Bi 3+ 、Fe 3+ 、Au 3+ in the identification of Sb(V) using Rhodamine B.
