Continuous dialysis of selected salts of sulphuric acid
Helena Bendova, Pavel Šnejdrla and Zden k Palaty

    The transport of selected salts of sulphuric acid (cobalt, copper, iron(II), manganese, nickel and zinc sulphate) through an anion-exchange membrane Neosepta-AFN was investigated in a countercurrent continuous dialyzer at various salt concentrations and volumetric liquid flow rates. The basic transport characteristics − the rejection coefficient of salt and the permeability of the membrane − were calculated from measurements at steady state. The salt concentration in model mixtures was changed in the limits from 0.1 to 1.0 kmol m−3 and the volumetric liquid flow rate of the inlet streams was in the limits from 8
