Continuous dialysis of sulphuric acid and magnesium sulphate

▶ The transport of sulphuric acid and magnesium sulphate through an anion-exchange membrane Neosepta-AFN was investigated in a two-compartment counter-current dialyzer with single passes at steady state. ▶ The dialysis process was characterized by the recovery yield of acid and the rejection coefficient of salt. ▶ Moreover, the simultaneous transport of acid and salt was satisfactorily quantified by four phenomenological coefficients, which are functions of acid and salt concentrations in the feed.
