Modeling of continuous diffusion dialysis of aqueous solutions of sulphuric acid and nickel sulphate

Original language description

At steady state, the simultaneous transport of sulphuric acid and nickel sulphate through an anion- exchange membrane Neosepta-AFN (Astom Corporation, Tokyo, Japan) was investigated in a two compartment counter-current dialyzer with single passes. The transport was quantified by the recovery yield of acid, rejection of salt and four phenomenological coefficients, which were correlated with the acid and salt concentrations in the feed. The phenomenological coefficients were determined by the numerical integration of the basic differential equations describing the concentration profiles of the components in the dialyzer. This integration was combined with an optimizing procedure. The experiments proved that the acid recovery yield is in the limits from 63 to 91 %, while salt rejection is in the limits from 79 to 97 % in the dependence on the volumetric liquid flow rate and composition of the feed.
