Název v původním jazyce

Continuous Dialysis of Hydrochloric Acid at Steady and Unsteady States

Popis výsledku v původním jazyce

The transport of hydrochloric acid through anion-exchange membrane Neosepta-AFN in a counter-current continuous dialyzer has been investigated. The basic transport characteristics of membrane/solution system - the overall dialysis coefficient and ermeability of the membrane - have been evaluated and compared at steady and unsteady states. 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 the optimizing procedure. It was found, that the values of the overall dialysis coefficient determined from measurements at unsteady state are very similar to those obtained at steady state. The overall dialysis coefficient of hydrochloric acid shows strong increase with increasing acid concentration in the feed and weak increase with increasing volumetric flow rate. Moreover, in the concentration range of hydrochloric acid from 0.2 to 3.2 kmol m-3,
