Electrodeionization removal of HCrO4- ions from diluted solution. Effect of membrane

Abstract

Transport of chromate ions in the systems involving granulated ionexchangers and anion-exchange membranes of different origin was researched under various voltage. The role of the membranes as sorption barrier was considered. The method that allows one to estimate mobility of sorbed ions through ion-exchanger bed has been proposed. Electrodeionization of Cr(VI)- containing solution using inorganic ion exchange materials was studied.
