【摘要】 研究了以10^-3M或10^-4M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。更多还原

【Abstract】 The potentiometric curves of 25 basic dyes and 19 quaternary ammonium salts ti-trated with orange Ⅳ (10^-3M or 10^-4M) have been recorded. A method for evaluatingthe potentiometric titration curves was suggested and their superiority sequences wereestablished. it was found that some of the curves may be applied in electrochemicalanalysis with higher sensitivity, and the structure of basic dyes and quaternary ammo-nium salts exerts an influence on the titration curve. The superiority sequences of thetitration curves would give a possible approach to find new electroactive substances foranion-selective electrodes.更多还原
