摘　　要：本文以实验为基础,提出了在进行定性分析时,用N—烯丙基—N′—(对苯磺酸钠)硫脲作掩蔽剂,消除一些离子的干扰.与传统的消除干扰的方法相比,具有条件容易控制,操作简便等优点.Based on experiments.the elimination of interference of some ions with N-ALLYL-N'-(Sodium p-phenyl-sulfonate)thiourea as sheltering agent while some ions are ana-lyzed qualitatively. This method provides significant advantages over traditional one easy to control the condition,simple and convenient to operate,etc.
