Abstract

The theoretical expression for the mass transfer of a 1-2 electrolyte in an electrodialysis cell was derived from the Nernst-Planck equation as (N/u) = 5.547(ReScde/L)^1/3, with the assumption that the rate-determining step is the ionic diffusion in the concentration boundary layer. The corresponding empirical correlation for the H2S04-glucose-xyiose system was found as eq 22 with a = 5.26 which was very close to the theoretical one. The effects of the concentration and temperature on the limiting current density were also studied. For the multicompartment electrodialysis, the maximum current efficiency of 51.5% was obtained with a flow rate of 6.95 X 10^-2 m/s and a H₂SO₄ concentration of 2.64%. The effects of flow rates on the current efficiency were also investigated. It was found that the current efficiencies were greater than 40% with the H2S04 concentrations of 1.4%-4.8% and current densities of 49-126 A/m².
