摘　　要：为解决水体污染日趋严重的问题,结合光催化降解有机物的研究前沿,设计了基于吸附与光催化协同效应的“纳米复合膜高效去除有机污染物”交叉性综合实验。该实验合成了带有羧酸根的聚合物p(MMA-AA),将其和聚醚砜(PES)及二氧化钛(TiO_(2))进行复合制成平板膜。实验结果表明,在没有光照的环境中,仅靠膜的吸附作用对污染物的清除效率较低。在光照作用下,羧酸根不断静电吸附罗丹明B,同时被TiO_(2)通过光催化降解,实现了污染物的快速清除。To solve the increasing problem of water pollution,based on the cutting-edge research in the photocatalytic degradation of organic compounds,this paper designs a cross disciplinary comprehensive experiment on the efficient removal of organic pollutants by nanocomposite membranes based on the synergistic effect of adsorption and photocatalysis.Polymer p(MMAAA)with carboxylate groups was experimentally synthesized and composite with PES and TiO_(2) to form a flat membrane.In an environment without light,relying solely on the adsorption of membranes has a lower efficiency in removing pollutants.Under the action of light,carboxylate groups continuously adsorb Rhodamine B through electrostatic adsorption,and are simultaneously degraded by TiO_(2) through photocatalysis,achieving rapid removal of pollutants.
