Competitive Transport of Hydrochloric Acid and Zinc Chloride through Anion-exchange Membrane

Popis výsledku v původním jazyce

Competitive transport of hydrochloric acid and zinc chloride has been investigated in a two-compartment mixed cell with an anion-exchange membrane Neosepta-AFN developed and produced by Tokuyama Soda Co., Ltd. These experiments have proved that hydrochloric acid permeates well through the membrane used but, on the other hand, zinc chloride is not effectively rejected. The rejection coefficient of zinc chloride has been found to be decreasing with increasing acid concentration but it increases with an increasing salt concentration. Furthermore, it has been found that the rejection coefficient for ZnCl2 is much lower than that for ZnSO4 (in the case of H2SO4-ZnSO4 system, R > 0.985). The further calculations concerning the ionic equilibria with sorptionisotherms for the HCl-ZnCl2 system, which has been experimentally measured, have revealed that very high flux of ZnCl2 is due to the fact that a considerable amount of zinc chloride in the membrane is in the form of a ZnCl3- complex, whic
