Effect of valences on removal of anionic pollutants using micellar-enhanced ultrafiltration
The feasibility of micellar-enhanced ultrafiltration (MEUF) for the removal of nitrate, chromate, and ferric-cyanide was investigated because of ionic competition to bind on the cetylpyridinium chloride micelles. In a single pollutants system, the order of removal efficiency was nitrate <chromate <ferriccyanide: this was coincidental with the order of valences of ions. In the tertiary pollutant system, the order was the same as the single pollutant system: nitrate <chromate <ferriccyanide. The inhibition of ferriccyanide on the removal of nitrate and chromate was clearly observed, but the inhibition of chromate on the removal of nitrate was lower than that of ferriccyanide.
