含有-N=N-NH-基团的试剂是镉、汞等金属元素的灵敏显色剂。为了探讨这类试剂的某些分析性能,合成了1-(4-安替吡啉)-3-(4-硝基苯基)-三氮烯(APNBT):
The reagent containing -N = N-NH- group is a sensitive developer of metal elements such as cadmium and mercury. In order to investigate some analytical properties of this kind of reagent, 1- (4-Antilopyran) -3- (4-nitrophenyl) -triazene (APNBT)
