Abstract

Electrodialysis (ED) and nanofiltration (NF) were adopted to separate monovalent and divalent ions (Na+/Mg2+, Cl-/SO42-). The results showed that DL2540 had a better separation efficiency for the rejection of divalent ions than NF270. The rejection of Mg2+ and SO42- were 98.1% and 80.5%, respectively. For ED, the separation factors were 2.5 and 40.0. The separation performance of Cl-/SO42- was better than that of Na+/Mg2+, the separation factors were 18.4 and 2.9 under 90% recover rate of Na+. Both methods had good separation effects of monovalent and divalent ions. ED could also realize ions concentration, while NF could not.
