Electrodeionization of li-containing solutions using ion exchange material based on tio2-mno2
(2018) Chaban, Mariya; Rozhdestvenska, Lyudmyla; Dzyazko, Yulia
In this work the problem of selective extraction of Li+ ions from combined solutions by electromembrane method is being solved. Sorbent based on lithium-substituted titanium manganese oxide was used. It is established that the function of the sorbent in the membrane system is reduced to the turbulization of the solution flow, but under the influence of alkalization of the solution near the surface of the sorbent granules, its sorption capacity increases with an increase in voltage from 3 to 20 V.
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.
