Removal of boron from water by donnan dialysis
(2006) Tor A.; Arslan G.; Cengeloglu Y.; Ersoz M.
Removal of boron from aqueous solution was studied through SB-6407 anion exchange membrane by Donnan dialysis method. The effects of concentration, pH, and accompanying anions on feed and receiver phase composition were investigated. The flux of boron with respect to the concentration, pH, and the effect of the accompanying anions (Cl- and SO4 -2) were obtained between (0.472 ± 0.011 - 6.825 ± 0.151)×10-8 mol.cm-2.s-1. With a fix pH 9.5 of the feed phase, the highest boron removal was obtained when pH of the receiver phase was 1. Additionally, transport of boron increased with increase of feed and recevier phase concentration and decreased in the presence of accompanying anions in the feed phase. The transport of boron was also correlated with the flux data and explained according to structure of membrane.
