Sažetak
A new anionic surfactant sensor has been prepared, based on 1, 3-didecyl-2-methyl-imidazolium-tetraphenylborate ion-exchange complex as sensing material incorporated into the plasticized PVC-membrane. The sensor exhibited Nernstian response (59.0 mV/decade) in the region between 2-10000 micromol/dm3 for dodecylsulfate and 61.6 mV/decade between 1-2000 micromol/dm3 for dodecylbenzen-sulfonate. The main application of the sensor described was indication of the end-point in ion-pair surfactant potentiometric titrations. The electrode showed satisfactory analytical performances within pH range 2.5 - 11. The potentiometric selectivity coefficients were determined by fixed interferent method. The sensor was also applied for potentiometric titration of some two-components mixtures.
