Oleophilic anion exchange resin membranes based on homogeneous cross-linked polystyrene membranes are described. The anion exchange membrane prepared was swollen with water-immiscible organic solvents such as nitrobenzene and was used as the ion-selective electrode membrane. The membranes wetted with the organic solvents showed good selectivity and could be used as sensitive membranes of anion-selective electrodes such as nitrate and Perchlorate ion selective electrodes. The selectivity of the membrane electrode can be adjusted by selecting an impregnating organic solvent.
