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[ClO4]. 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/closedAccesscalix[4] areneperchloratePVC membrane ion-selective electrodepotentiometryArticle323323332Q3WOS:000257116100006Q3
