The electrode of the optimum characteristic had a composition of 1% ionophore, 66% o-NPOE, and 33% PVC. This electrode exhibited a linear response over the range 1.0 x 10{-1}-1.0 x 10{-5} M of perchlorate with a slope of 48.7. ± 0.5- mV per p[Cl04]. The effects of the pH and the membrane composition were also investigated. The lifetime of the electrode was at least 4 months and its response time was 10-15 s. The selectivity coefficients of some anions were calculated by the matched potential method.eninfo:eu-repo/semantics/openAccessMühendislikKimyaArticle323323332
