Electrodeionization removal of HCrO4- ions from diluted solution. Effect of membrane
(2016) Dzyazko, Yulia; Arar, Özgur; Rozhdestvenska, Lyudmyla; Vasilyuk, Sergey
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.
Sorption removal of uranium (VI) compounds with organic-inorganic ion-exchangers
(2016) Perlova, Natalia; Perlova, Olga; Halutska, Iryna; Dzyazko, Yulia; Palchik, Alexey; Sazonova, Valentina
Organic-inorganic composites based on ion exchange resins containing zirconium hydrophosphate (cation-exchanger) and hydrated zirconium dioxide (anion-exchanger) were applied to removal of soluble U(VI) compounds from modeling solutions. The advantages of the composites over the pristine resins are more significant sorption capacity, higher sorption rate and more facile regeneration.
