Dialysis of hydrochloric acid in the presence of potassium chloride. Permeability of anion-exchange membrane for Cl- ions

Popis výsledku v původním jazyce

The simultaneous transport of hydrochloric acid and potassium chloride 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 yield and the rejection coefficient of salt - were evaluated from the measurements at steady state. Furthermore, the dialysis process was characterized by the permeability coefficient of the membrane towards to Cl? ions. The initial hydrochloric acid concentration in model mixtures was changed in the limits from 0.1 to 1.0 kmol m-3 and that of potassium chloride was changed in the limits from 0.1 to 1.0 kmol m-3. Beside the dialysis experiments with HCl+KCl mixtures, also experiments with single component solutions were carried out. The volumetric liquid flow rate of the inlet streams was in the limits from 8 x10-9 to 24 x10-9 m3 s-1. Under the experimental conditions given, the ac
