研究了以10~(-3)M或10~(-4)M橙黄Ⅳ滴定25种碱性染料和19种季铵盐的电势滴定曲线。提出了一种估价电势滴定曲线的方法并确定了这些曲线体系的优劣次序。讨论了碱性染料和季铵盐结构对电势滴定曲线的影响。结果表明,有些曲线可用于较高灵敏度的分析,电势滴定曲线的优劣次序可为寻找阴离子选择电极的电活性物质提供途径。
The potential titration curves of 25 basic dyes and 19 quaternary ammonium salts titrated with 10 ~ (-3) M or 10 ~ (-4) M Huanghuang Ⅳ were studied. A method of evaluating the potential titration curve is proposed and the order of the advantages and disadvantages of these curve systems is determined. The effects of basic dyes and quaternary ammonium salt structures on potential titration curves are discussed. The results show that some of the curves can be used for the analysis of higher sensitivity. The order of the potentiometric curves can provide a way to find the electroactive substances of the anion selective electrode.
