| 摘 要： | 以丙烯酸-马来酸共聚物(PMA-100)为络合剂,研究聚合物络合金属离子的强化超滤处理含镍废水,研究聚合物与金属离子质量比(mP/mM)、溶液pH、盐浓度、操作压力、运行时间等对镍离子截留率的影响。研究结果表明:溶液pH对金属离子截留率影响很大,在一定mP/mM下,pH在3～7的范围内,适当提高溶液pH有利于镍离子的截留;在一定pH下,镍离子的截留率R随mP/mM的增加而增加;溶液pH=6.0,mP/mM=7时,镍离子的截留率可达到99%以上;NaCl和Na2SO4的存在使镍离子的截留率有所降低。

| 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/mM,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. |
