Permeability of Anion-exchange Membrane for Cl- Ions. Dialysis of Hydrochloric Acid in the Presence of Nickel Chloride
Original language description
Using a conventional two-compartment cell with stirrers the separation of an aqueous solution of HCl-NiCl2 by an anion-exchange membrane Neosepta-AFN was investigated. The dialysis process was characterized by the permeability coefficient of the membranetowards to Cl- ions. This quantity was determined by the numerical integration of equations, which describe the time dependence of the total concentration of Cl- ions in compartment initially filled with stripping agent (water), combined with an optimizing procedure. The analysis of the experimental results showed that this permeability coefficient is a satisfactory characteristic for the process studied. It can be graphically correlated with the initial acid and initial salt concentrations in the compartment initially filled with acid+salt mixture.

Permeabilita anion-výměnné membrány pro Cl- ionty. Dialýza kyseliny chlorovodíkové v přítomnosti chloridu nikelnatého
Czech description
S použitím konvenční dvoukomorové míchané dialyzační cely byly sledována separace vodného roztoku HCl+NiCl2. Proces dialýzy byl charakterizován koeficientem permeability membrány pro Cl- ionty. Tato veličina byla určena numerickou integrací rovnic popisujících časovou závislost celkové koncentrace chloridových iontů v části cely původně naplněné stripovacím činidlem. Tato integrace byla následována optimalizační procedurou. Experimenty prokázaly, že koeficient permeability membrány je dostatečnou chrakteristikou daného procesu.
