合成洗涤剂的主要成分十二烷基苯磺酸钠是环境污染物之一,常规采用的次亚甲蓝比色分析法操作繁琐,且使用氯仿造成二次污染。若采用离子电极法分析,不仅操作简便快速,而且避免氯仿污染,因此探求性能优良的洗涤剂阴离子选择电极是一项很有意义的工作,对于十二烷基苯磺酸根(DBS~-)离子选择电极的研制,国内外已有报 Sodium dodecyl benzene sulfonate, the main component of synthetic detergent, is one of environmental pollutants. Conventional sub-methylene blue colorimetric method is cumbersome to operate and uses chloroform to cause secondary pollution. If the ion-electrode method is used, not only the operation is quick and easy, but also the pollution of chloroform is avoided. Therefore, it is a significant work to find the detergent anion selective electrode with good performance. For dodecyl benzene sulfonate (DBS ~ -) ion Selection of electrode development, both at home and abroad have been reported
