混合胶束对铟(Ⅲ)-邻氯苯基荧光酮显色反应的影响及其作用机理的研究

Influence of Mixed Micelle on the Color Reaction of Indium (Ⅲ) With 2,6,7-Trihydroxy-9-(o-chlorophenyl)fluorone

比较了8种非离子表面活性剂与CTMAB形成的混合胶束对In(Ⅲ)-邻氯苯基荧光酮显色反应的作用。以CTMAB-TweenS0的增敏效果最佳。研究了In(Ⅲ)-o-Cl-PF-CTMAB-Tween80体系的形成条件及混合胶束的作用机理。以拟定的方法测定复杂试样中的铟,结果很满意。

After comparing the influences of eight mixed micelles of non-surfactants and CTMAB on the sensitized coordination compound of indium(Ⅲ) with 2,6,7-trihydroxy-9-(o-chlorophenyl)fluorone, it is found that the mixture of CTMAB and Tween-80 is the most suitable one. The optimum conditions of coordination compound and its formation mechanism have been studied. This method can be used to determine microamount of indium in the complex samples with high accuracy and precision.
