Název v původním jazyce

Continuous dialysis of sulphuric acid and magnesium sulphate

Popis výsledku v původním jazyce

The competitive transport of sulphuric acid and magnesium sulphate through an anion-exchange membrane Neosepta-AFN (Astom Corporation) was investigated in a two-compartment counter-current dialyzer with single passes at steady state. The dialysis processwas characterized by the recovery yield of acid and the rejection coefficient of salt. The experiments proved that the recovery yield of acid was in the limits from 61 % to 90 %, while the rejection coefficient of magnesium sulphate was in the limits from 87 % to 97 %. 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. For this purpose, two ordinary differential equations describing the steady-state concentration profiles of both the components in both the compartments of the dialyzer were numerically solved in the connection with an optimizing procedure.
