近十年来,国际上曾对阴离子洗涤剂离子选择性电极开展了不少研究,如采用十六烷基吡啶、三辛基甲基铵、Ferrorin、Hyamine、结晶紫等阳离子染料为配对阳离子,分别试制了十二烷基硫酸根,辛基硫酸根和十二烷基苯磺酸根离子选择性电极。但是这些电极的稳定性和重现性都不够好,至多只能用作电位滴定的指示电极,用于直接电位法的尚未见有报导。我们试验了长碳链的季铵阳离子三庚基十二烷基铵与阴离子洗涤耕十二烷基苯磺酸形成的离子对化合物作为电极的活性材料,试制了新的液膜型阴离子洗涤耕 In recent ten years, many international researches have been done on anionic detergent ion-selective electrodes. For example, cationic dyes such as cetylpyridinium, trioctylmethylammonium, Ferrorin, Hyamine and crystal violet are paired cations, Dodecyl sulfate, octyl sulfate and dodecylbenzenesulfonate ion selective electrodes were prepared. However, the stability and reproducibility of these electrodes are not good enough, at most, they can only be used as the indicator electrode for potentiometric titration. There has been no report on the direct potential method. We tested a long carbon chain of the quaternary ammonium cationic heptyl dodecylammonium and anionic ammonium tungstate dodecyl benzene sulfonic acid formed as the active material of the electrode, the trial of a new liquid membrane anion washing
