摘要
自 8 0年代以来 ,共合成了苯并噻唑偶氮苯类试剂近 50种 ,在环保废水测定、合金中痕量元素测定等应用效果满意。苯并噻唑偶氮苯类试剂可与 Co( )、Cu( )、Fe( )、Fe( )、Ni( )、Pd( )等多种离子发生配位显色反应。在表面活性剂或有机溶剂存在下 ,具有较高的灵敏度和选择性 ,在分析领域得到广泛应用 。
Since the 80s,nearly 50 kinds of benzothiazolylazobenzenes have been synthesized and put into successful use in the analysis of environmental waste water and of trace elements in alloys.The benzothiazolylazobenzenes undergo complexing reactions with Co(Ⅱ)、Cu(Ⅱ)、Fe(Ⅱ)、Fe(Ⅲ)、Ni(Ⅱ)、Pd(Ⅱ) and some other ions;and in the presence of surfactants or organic solvents,it shows high sensitivity and selectivity.It has been widely used in the field of analysis and has its practical meanings.
