摘　　要：本文详细地研究了在高氯酸介质中三氯偶氮胂与铋显色反应条件及配合物的组成。在此基础上拟定了用巯基棉富集水中痕量铋,三氯偶氮胂光度法测定其含量的新方法。The colour reaction of trichloroarsenaze with Bi has been studied. A large amount of weight metal ions does not interfere for the determination in 0. 72mol/L HC10_4. Interfercefrom other metal ions can be separated with sulfhydryl cotton. It has been applied to determinetrace of Bi in water. The method is simple and accurate.
