Transport of salts of sulphuric acid through an anion-exchange membrane in continuous dialyzer
Original language description
The transport of salts of sulphuric acid (copper, iron(II), nickel and zinc sulphate) through an anion-exchange membrane Neosepta-AFN was investigated in a counter-current continuous dialyzer for various salt concentrations and volumetric liquid flow rates. The basic transport characteristics, the rejection coefficient of salt and the permeability of the membrane, were evaluated from the measurements at steady state. Under the experimental conditions given, the rejection coefficient for salts tested wasin the range from 65% to 94%, the lowest values were obtain for iron(II) sulphate, while the highest for copper sulphate. The maximum rejection of salt can be reached at high volumetric liquid flow rates of the feed and high initial salt concentration.The permeability of the Neosepta-AFN membrane for the individual salts lies in a range from 0.5x10E-7 m/s to 1.8x10E-7 m/s and it can be described by the following series: P(FeSO4) < P(NiSO4) < P(ZnSO4) < P(FeSO4).
