用马来酸-丙烯酸共聚物(PMA-100)作络合剂，采用PVB中空纤维膜，研究络合-超滤处理含锰废水。测定了高聚物的羧基含量以及Mn(II)与PMA-100的络合反应速率，研究聚合物与重金属质量比(P/M)、pH、外加盐浓度等因素对锰离子截留率(R)和膜通量(J)的影响。结果表明：高聚物中羧基含量为9.5 mmol/g，对Mn(II)质量浓度为10 mg/L的模拟废水，在pH=6.0时，Mn(II)与PMA-100的络合在5 min内基本可完成，络合率达99.6%。在一定P/M下，pH在2.5~7.0范围内，截留率和膜通量均随着pH的增加而增大；在一定pH下，截留率随着P/M的增加而增加，但膜通量基本不变。外加盐的存在使截留率下降，在同样离子强度下，CaCl2的影响远大于NaCl的。

Copolymer of maleic acid and acrylic acid (PMA-100), combining with polyvinyl butyral (PVB) ultrafiltration membrane was used for the removal of Mn(II) from waste water by complexation-ultrafiltration. The carboxylic group content of PMA-100 and the rate of complexation reaction were measured. Effects of the mass ratio of PMA-100 to Mn(II) (n), pH, background electrolyte, etc on the rejection rate (R) and permeate flux (J) were investigated. The results show that carboxylic group content of PMA-100 is 9.5 mmol/g. The complexation of Mn(II) with PMA-100 is rapid and completed within 5 min at pH 6.0. Both R and J increase with pH increasing in the range of 2.5-7.0, and R increases with the increase of n at pH 6.0 while J is little affected. The background electrolyte leads to the decrease of R, and CaCl2 has much greater effect on R than NaCl at the same ionic strength.
