摘要
By using some basic physico-chemical data, the fluxes (or transference numbers) of proton and hydroxyl ion in the stationary electrolysis are compared with the relative judgment expressions which were defined from moving chemical reaction boundary equations. The results reveal that the quasi/equal fluxes of hydrogen and hydroxyl ions are present in the neutralization reaction boundary formed with pure acid and base, in stationary electrolysis and in Svensson's isoelectric focusing (IEF). Thus, the findings are completely in agreement with the inference - the existence of quasi/equal fluxes of proton and hydroxyl ion in stationary electrolysis and Svensson's IEF- which is based upon the conditional equations for the anolyte and catholyte (equivalently, stationary neutralization reaction boundary equations) and upon the facts that the pH gradients in Svensson's IEF are quasi-stable, but not complete stable.
