The sensor exhibited Nernstian response (59-61mV/decade) in the region between 10-3-10-5mol/l for dodecylsulfate. The potentiometric selectivity coefficients were determined by fixed interferential method. Application of these electrodes to the analysis of some products containing anionic surfactants has been realized and results have been compared with the two-phase titration methodrosurfactanţi anionicisoluţii de laurilsulfat de sodiuelectroziArticle
