摘要
分别以邻苯二胺、间苯二胺、对苯二胺为水相单体,均苯三甲酰氯(TMC)为油相单体,聚醚砜超滤膜为基膜,界面聚合法制备了复合纳滤膜。在纳滤膜对Na2SO4,MgSO4,MgCl2和NaCl四种盐的脱盐率中,间苯二胺膜最高,对苯二胺膜居中,邻苯二胺膜最差;在纳滤膜耐氯性能方面,对苯二胺最佳,邻苯二胺居中,间苯二胺最差。综合纳滤膜的分离性能和耐氯性能,对苯二胺为最优的单体。
Composite nanofiltration membranes were fabricated through interfacial polymerization.Membranes were prepared with diamine as aqueous monomer and trimesoyl chloride（TMC） as organic monomer on the support of polyethersulfone（PES） ultrafiltration membranes.Three different diamines were utilized as aqueous monomer respectively.They are o-phenylenediamine,m-phenylenediamine and p-phenylenediamine.The separation performance and the chlorine resistance of these membranes were compared.The salts rejection on four different salts Na2SO4,MgSO4,MgCl2 and NaCl were measured.The order was m-phenylenediaminep-phenylenediamineo-phenylenediamine.The order of chlorine resistance was p-phenylenediamineo-phenylenediaminm-phenylenediamine.Combining the performance of salts rejection with chlorine resistance p-phenylenediamine was the optimal monomer for polyamide nanofiltration membranes.
