采用液相诱导分离（LIPS）技术，在聚醚砜（PES）基体中共混聚多巴胺包被氧化铁（Fe3O4@PDA）纳米颗粒，成功制备了同时吸附重金属离子和催化降解有机污染物的新型复合膜。通过引入Fe3O4@PDA纳米颗粒，制备的复合膜的渗透率显著提高，因为Fe3O4@PDA纳米颗粒表面的亲水性涂层能够在LIPS过程中在PES基质和纳米颗粒之间产生更多的微孔结构。含有20 wt% Fe3O4@PDA纳米粒子的复合膜的水通量高达2640 L∙m−2∙h−1∙bar−1，是PES空白膜的6倍。基于类芬顿反应机理，复合膜具有高效、可重复的吸附去除重金属离子和催化降解有机污染物的性能。该复合膜具有同时催化降解有机污染物和吸附重金属离子的多种功能，为造纸、皮革、纺织印染等难处理废水的处理提供了新的途径。此外，本工作提出的一步制得大透性和高分离效率复合膜的策略易于规模化。
Novel composite membranes are successfully developed for simultaneous adsorption of heavy metal ions and catalytic degradation of organic contaminants by blending polydopamine-coated ferroferric oxide (Fe3O4@PDA) nanoparticles in polyethersulfone (PES) matrix via liquid-induced phase separation (LIPS) method. The permeabilities of the as-fabricated composite membranes are significantly improved by introducing Fe3O4@PDA nanoparticles, because the hydrophilic coating on the surface of Fe3O4@PDA nanoparticles enables to generate more microporous structures between the PES matrix and nanoparticles during the LIPS process. The composite membrane containing 20 wt% Fe3O4@PDA nanoparticles shows water flux as high as 2640 L∙m−2∙h−1∙bar−1, which is six times larger than that of PES blank membrane. The composite membranes exhibit efficient and repeatable performances for simultaneous adsorptive removal of heavy metal ions and catalytic degradation of organic contaminants based on the mechanism of Fenton-like reaction. The proposed composite membranes with multifunction of simultaneous catalytic degradation of organic contaminants and adsorption of heavy metal ions provide a new pathway to deal with some hard-to-be-treated wastewaters from papermaking, leather, textile printing-dyeing industries, and so on. Furthermore, the proposed one-step strategy for fabricating composite membranes with both large permeability and high separation efficiency in this work is easy to be scaled up.
