阳离子表面活性剂缔合型离子选择电极,国外近年来有若干报道,所用离子交换体有四苯硼酸盐(及其衍生物)、十二烷基磺酸盐、四氮茂等,电极的线性下限一般为10~(-5)M。Maeda等制备了以冠醚为活性材料的中性载体电极,对季铵阳离子的线性响应下限达到2×10~(-6)M。国内尚无有关阳离子表面活性剂电极的公开报道。本文报道了一种以直链烷基苯磺酸盐为离子交换体、以硝基苯和邻苯二甲酸二(2— Cationic surfactant associated ion selective electrode, there are several foreign reports in recent years, the ion exchangers used tetraphenylborate (and derivatives), dodecyl sulfonate, four nitrogen Mao, etc. The lower limit of linearity is generally 10 ~ (-5) M. Maeda et al prepared a neutral carrier electrode with crown ether as the active material and had a lower limit of linear response to quaternary ammonium cations of 2 × 10 ~ (-6) M. There is no public report about cationic surfactant electrode in China. This paper reports a linear alkyl benzene sulfonate ion exchangers, nitrobenzene and phthalic acid bis (2-
