摘要
A TTF-TCNQ/PVC composite electrode is proposed as a voltammetric cation and anion sensor. The electrode relies on the principle that, during redox processes involving the TCNQ(0/-) couple for cations and the TTF+/0 couple for anions, electrolyte ions are included into lattice sites in the charge neutralization process. This voltammetric ion-sensor provides results that are similar to those of sensors based on two electrodes (viz. one modified with TCNQ for cations and another modified with TTF for anions) but with some practical advantages over them.
