表面活性剂对3,5-二溴-PADAP与锌(Ⅱ)显色反应产生增敏的原因探讨

Study on the Reason for the Sensitivity Enhancement of Colour Reaction Zinc(Ⅱ)with 3,5-di Br-PADAP in the Presence of Surfactant

本文探讨了阳离子表面活性剂ＣＴＭＡＢ及阳离子—非离子型混合表面活性剂ＣＴＭＡＢ—ＴｒｉｔｏｎＸ－ １００ 对锌（ Ⅱ） 与３ ，５－ 二溴－ ＰＡＤＡＰ显色反应产生增敏作用的原因。

The cationic surfactant CTMAB and cationic—nonionic mixed surfactant CTMAB—Triton X-100 can enhance the sensitivity of the colour reaction of Zinc(Ⅱ) with 3,5-diBr-PADAP.The reason for the sensitivity enhancement is discussed in this paper.
