Cross-flow micellar-enhanced ultrafiltration for removal of nitrate and chromate: competitive binding
Feasibility of cross-flow micellar-enhanced ultrafiltration was investigated to remove chromate and nitrate from water system using a cationic surfactant, cetylpyridinium chloride (CPC). Removal of chromate with -2 as valence was higher than that of nitrate with -1 as valence in the conditions of co-existence of chromate and nitrate. Removal of nitrate was significantly inhibited by co-existence of chromate because of competitive binding to CPC micelles between chromate and nitrate, while that of chromate was only slightly inhibited by nitrate.
