Název v původním jazyce

Continuous Dialysis of Inorganic Acids: Permeability of Neosepta-AFN Membrane

Popis výsledku v původním jazyce

The transport of phosphoric and hydrochloric acids through anion-exchange membrane Neosepta AFN in a counter-current continuous dialyzer has been investigated. The basic transport characteristics of membrane/solution systems - the overall dialysis coefficient and the permeability of the membrane - have been evaluated at steady state. The determination of these characteristics is based on the numerical integration of the set of differential equations describing the concentration profiles in both compartments of the dialyzer followed by an optimizing procedure. It was found, that the permeability of membrane is strongly affected by acid concentration - for phosphoric acid it decreases with an increasing acid concentration and for hydrochloric acid it increases with an increasing acid concentration. Moreover, except for the lowest acid concentration used, the permeability for phosphoric acid is lower than that for hydrochloric acid - in the concentration range of acid from 0.2 to 3.0 kmol
