摘要
采用液相氧化沉淀法制备了氧化高银,间苯二胺(MPD)、均苯三甲酰氯(TMC)分别为水相和油相反应活性单体,通过界面聚合法制备了氧化高银/聚酰胺复合膜。研究了氧化高银质量分数对膜分离性能和抗菌性能的影响。利用扫描电子显微镜(SEM)、膜性能评价仪、接触角测量仪等对膜表面形貌、分离性能、亲水性进行表征,通过抑菌圈法对膜的抗菌性能进行测试。结果表明:当氧化高银质量分数为0.3%时,聚酰胺复合膜的分离性能最佳,水通量达161.48 L/(m^2·h^(-1)),截留率为88.5%,且具有抗菌性。
Divalent silver oxide is prepared by liquid phase oxidizing sedimentation. With m-phenylenediamine( MPD) and terephthaloyl chloride( TMC) as monomers in aqueous phase and organic solvent phase,respectively,the divalent silver oxide / polyamide composite membranes are fabricated by using interfacial polymerization method. The effect of the mass fraction of divalent silver oxide on the membrane separation and antibacterial properties is studied. The membrane surface morphology,separation performance and hydrophilicity are characterized by scanning electron microscopy( SEM),membrane performance evaluation instrument and contact angle measuring instrument,respectively.Antibacterial properties of the membrane are tested by the inhibition zone method. The results show that the separation performance of polyamide composite membrane is the best when the content of divalent silver oxide is 0. 3%. The water flux is 161. 48 L / m2·h- 1. The rejection is 88. 5% and antibacterial property is also obtained.
