Makovetskaya, L. I. published the artcileIon-selective electrodes with anionic tenside function for detergent analysis, Quality Control of 518-67-2, the publication is Seifen, Oele, Fette, Wachse (1991), 117(15), 565-71, database is CAplus.
The electrochem. characteristics of dodecyl sulfate-, and dodecylbenzene sulfonate-selective electrodes with polymer membranes on the base of ion associations of anionic tensides and cetylpyridinium, tetrahexadecylphosphonium (I), giamin 1622, etonium, and dyes like methylene blue (II) and dimidium bromide (III) were studied. Calibration curves are presented. The most stable electrodes (1400-1500 measurements) were these of associations of anionic tensides with I and dyes (II and III) obeying the Nernst relation in a broad range of tenside concentration and pH (1-12). Results from potentiometric titrations of Na alkylbenzene sulfonates and Na alkyl sulfates with all investigated electrodes met the results from conventional 2-phase titrations
