Design of ionophore-free H+-selective solvent polymeric membranes for further biomedical applications
Ionophore-free H+-selective solvent polymeric membrane electrodes based on aminated poly(vinyl chloride) (PVC-NH2) are studied. Among the large number of amino-PVC derivatives, the electrodes fabricated from piperazine-modified PVC show the best analytical performances. The new pH electrodes exhibit a Nernstian response between pH 4 and pH 12, and their selectivity coefficients toward biologically interesting cations match the corresponding values of H+ electrodes based on TDDA or ETH 5294. The new membrane material offers additional prospects for ion-selective electrode fabrication with technologies used in microelectronic device development. © 1993.
