摘　　要：综述了近 10年来三氮烯类试剂的合成方法和在环境样品分析中的应用。按三氮烯类试剂合成的方法进行分类 ,分别为在亚硝酸钠和盐酸作用下重氮化的试剂 ,在亚硝酰正离子作用下重氮化的试剂 ,在亚硝酸正丁脂作用下重氮化的试剂 ,此类试剂灵敏度高 ,选择性好 ,广泛应用于被镉、汞等过渡金属离子污染的环境样品的分析中。This paper summarizes the compound method and the application of triazene reagents in surrounding samples in the past ten years. It also classifies them in accordance with the compound method of triazene reagents as follows: reagents diazotizated with sodium nitrite and muriatic acid, reagents diazotizated with nitrosyl positive ion, reagents diazotizated with n-butyrate nitrite.These reagents with high sensitivity and good choice have been widely applied to the determination of microa mounts of cadmium and mercury in surrounding samples with pollution.
