Separation of sodium and calcium cations by electrodialysis with ion-exchange membranes
Keywords:
separation of ions, electrodialysis, complexation, ion-exchange membrane.Abstract
A method of separation of alkaline and earth-alkaline metals by electrodialysis with ionexchange
membranes was introduced. Method is possible to get complete separation of investigated ions
in consequence of overcharge of the earth-alkaline cation metal in complexation with
ethylenediaminetatraacetic acid (EDTA) and following migration of the alkaline metal cation through
cation-exchange membrane while anion, which combinated with EDTA, migrates through anionexchange
membrane
