초록

The feasibility of PENTANOX 4X for the simultaneous removal of nitrate and phosphate was investigated using micellar-enhanced ultrafiltration. Because PENTANOX 4X has cationic property at low pH, anionic contaminants can be bound to PENTANOX 4X micelle by electrostatic interaction. At pH 3, 90% of nitrate and 72% of phosphate were removed by 27 mM of PENTANOX 4X, which were equivalent to 20 mM of CPC. PENTANOX 4X of > 80 % was rejected by ultrafiltration membrane and did not make any counter-ion such as chloride for CPC which might cause second-pollution.
