Abstract
A new anionic surfactant sensor has been prepared, based on trinuclear chromium(III) pivalate as sensing material incorporated into the plasticized PVC-membrane. 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 method
