摘要
合成了３种带有胂酸基功能团的苯基重氮氨基偶氮苯类试剂，研究了其性质及其与Ｃｄ（Ⅱ）、Ｈｇ（Ⅱ）、Ａｇ（Ⅰ）、Ｃｕ（Ⅱ）、Ｎｉ（Ⅱ）等离子的显色反应。在表面活性剂ＴｒｉｔｏｎＸ－１００存在下３种试剂与上述离子均有很高的反应灵敏度。讨论了取代基对试剂反应性能的影响。
Three triazenediyl reagents which contain arsons functional group, such as 4-methyl-2-arsonophenylde azoaminoazobenzene, etc. were synthesised.Their properties and color reactions with Cd(Ⅱ),Hg(Ⅱ),Ag(Ⅰ),Cu(Ⅱ)and Ni(Ⅱ)were studied.In the presence of Triton X-100 the sensitivities of these reactions are very high,The effects of substituents on the proper ties of these reagents were discussed.
