丙烯酸-马来酸共聚物强化超滤处理含镍废水
Treatment of wastewater containing nickel ions by polymer enhanced ultrafiltration with copolymer of acrylic acid-maleic acid
摘要
Abstract
The treatment of wastewater containing nickel ions by polymer enhanced ultrafiltration was studied using copolymer of acrylic acid-maleic acid (PMA-100) as complexing agent. Effects of mass ratio of polymer to metal (mp/Mm). Ph, salt concentration, transmembrane pressure and time on the retention of nickel ions were investigated. The results show that the retention of nickel ions depends strongly on Ph and increases with the increase of Ph in the range from 3 to 7 at a certain mp//Nm, and increases with the Mp/Mm at a certain Ph. The retention can arrive at over 99% at Ph=6.0 and Mp/Mm =7. The retention of nickel ions decreases slightly with the addition of sodium chloride or sodium sulfate.关键词
