Limits of detection and selectivity coefficients of a PVC-based anion-selective electrode.
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 + radicalC (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).
