Electrodialytic whey demineralization involving polymer-inorganic membranes, anion exchange resin and graphene-containing composite
Electrodialysis of cheese whey was performed using polymer membranes modified with zirconium hydrophosphate (cation exchange separator) and hydrated zirconium dioxide (anion exchange material). Both neutral and acidic solutions were used as a concentrate. As found, a 0.1 M HCl solution is...

| description | Electrodialysis of cheese whey was performed using polymer membranes modified
with zirconium hydrophosphate (cation exchange separator) and hydrated
zirconium dioxide (anion exchange material). Both neutral and acidic
solutions were used as a concentrate. As found, a 0.1 M HCl solution is
preferable: the current efficiency towards mineral components and
desalination degree reach 75-81 % and 90 % respectively, when the current
does not exceed limiting current for cations. Anion exchange resin, as well
as the composite containing zirconium dioxide and oxidized graphene, were
involved in desalination. The composite adsorbs preferably cations,
adsorption of anions is depressed. Its adsorption capacity is 1.2 (K+) and
0.25 (CL-) mmol g-1. Whey passed subsequently through the electrodialysis
cell and beds of these materials. This approach allowed us to achieve the
demineralization degree of 99%, and minimize losses of organic substances.
Adsorption materials can be used repeatedly. The advantage of the composite
over ion exchange resins is facile regeneration. |
