摘要
在三氮烯类试剂的基础上 ,合成新显色剂 2 ,6 -二溴 -4 -羧基苯偶氮重氮氨基苯偶氮苯 (BCADAB) ,并运用元素分析和红外光谱对试剂的结构进行鉴定。同时对该试剂的物理特性、化学特性、紫外吸收光谱、离解常数以及该试剂和其它镉试剂与Cd(Ⅱ )
Based on the triazene reagent, a new chromogenic reagent\_\_2,6-dibromo-4-carboxylbendiazoaminoazobenzene is synthesized. Its structure is identified by means of elemental analysis and infrared spectrophotometry. Its physical characteristics, chemical characteristics, Uitraviolet absorption spectrum, acid dissociation constant and characteristics contrast of chromogenic reaction with Cd(Ⅱ) are also studied.
