A membrane-based ion-selective electrode (ISE) has been developed for the trace-level determination of Cs þ in aqueous samples. A systematic evaluation of several ionophores was performed, examining the effect of membrane plasticizer and ion exchanger on sensor selectivity. Poly(vinyl chloride) (PVC)-based ion-selective membranes of conventional composition containing calix[6]arene hexaacetic acid hexaethylester as ionophore (Cs I, 10 mmol/kg), bis(2-ethylhexyl) sebacate (DOS, 66 wt%) as… Expand
