All-Solid-State PVC Membrane $ Ag^{+} $-Selective Electrodes Based on Diaza-18-Crown-6 Compounds

Abstract. Two diaza-crown ether compounds were synthesized and evaluated as $ Ag^{+} $-selective carriers in polyvinylchloride (PVC) membrane electrodes of solid-state type. The all-solid-state PVC membrane electrode based on N,N-Dibenzyl-dibenzo-diaza-18-crown-6 exhibited a super-Nernstian response (75±10 mV per decade) over the concentration range of 1×$ 10^{−1} $ to 7×$ 10^{−6} $ M of $ Ag^{+} $ ion and a detection limit of 3×$ 10^{−6} $ M, at a wide range of pH (pH 4–7). The response time of the electrode was fast (less than ∼10s), and it can be used for three months without any significant deviation in potential. The proposed all-solid-state PVC membrane electrodes revealed high selectivity toward $ Ag^{+} $ ion with respect to alkali, alkaline earth, heavy and transition metal ions. A flow-through cell of all-solid-state PVC membrane $ Ag^{+} $-selective electrode based on N,N-Dibenzyl-dibenzo-diaza-18-crown-6 has also been prepared and applied for flow-injection analysis of $ Ag^{+} $ ion in solution..
