摘要: Four effects providing overlimiting current transfer in ion-exchange membrane systems are examined. Two of them related to water splitting: the appearance additional carriers (H+ and OH- ions) exaltation effect. others due coupled convection partially destroying diffusion boundary layer: gravitational electroconvection. Three anion-exchange membranes, which differ surface morphology nature sites within a layer, The ion across these membranes NaCl solutions is studied by voltammetry, chronopotentiometry, pH-metry. By excluding splitting convection, it shown that main mechanism mass narrow cells at low salt concentrations reasons explaining why suppresses electroconvection discussed. scenario development potential oscillations with growing time compared described theoretically Rubinstein Zaltzman.
