Desalination of glycerol-water solutions by electrodyalysis using the organo-inorganic membranes

The organo–inorganic ion exchange membranes based on heterogeneous membrane materials and inorganic ion exchangers (zirconium hydrophosphate and hydrated zirconium dioxide) have been developed for electrodialysis desalination of glycerol–water solutions. It was shown that the electrodialysis efficie...

Description
Summary:The organo–inorganic ion exchange membranes based on heterogeneous membrane materials and inorganic ion exchangers (zirconium hydrophosphate and hydrated zirconium dioxide) have been developed for electrodialysis desalination of glycerol–water solutions. It was shown that the electrodialysis efficiency with pristine polymer membranes decreases with time due to formation of deposit directly in the membrane pores. In contrast, the organo–inorganic membranes exhibit resistance to poisoning by organic substances, and the current yield during the electromembrane treatment can reach 95–98%.
