摘要: Anion transfer processes at a liquid|liquid interface were studied with an interdigitated gold band array electrode. The organic phase, 4-(3-phenylpropyl)-pyridine containing Co(II)phthalocyanine, was immobilised as random droplets the electrode surface and then immersed into aqueous electrolyte. Oxidation of Co(II)phthalocyanine generator shown to be associated anion from phase. corresponding back reduction collector expulsion delayed by anion/cation diffusion time across interelectrode gap. A working curve based on finite difference numerical simulation model employed estimate apparent coefficients for anions in phase (PF6−
