eng	Transport of sulphuric acid and copper sulphate in continuous dialyzer	The simultaneous transport of sulphuric acid and copper sulphate through an anion-exchange membrane Neosepta-AFN was investigated in a counter-current continuous dialyzer for various acid/salt concentration ratios and volumetric liquid flow rates. The basic transport characteristics - the acid recovery, the rejection coefficient of salt and the overall dialysis coefficient - were evaluated from the measurements at steady state. Under the experimental conditions given, the acid recovery was found to be in the limits from 67% to 91% and the rejection coefficient was in the range from 74% to 96%. Nevertheless the results obtained showed that for H2SO4/CuSO4 mixture the Neosepta-AFN membrane can be considered a good separator.
