Abstract

Abstract A PVC-based anion-selective electrode was constructed with use of Capriquat as ion-exchanger. Experimental data were in good agreement with E = E 0 - ( RT/F)ln( C + √ C 2 + A x )/2. The parameter A x governs the limit of detection. It was experimentally shown that A x was related to the selectivity coefficient K xy by K xy = A y/ A x.
