聚酰胺胺改性的中空纤维膜可有效用于重金属离子的回收 并具有高重复利用率

lijian200511

用聚酰胺胺改性的中空纤维膜表现出很强的与铜离子，铅离子和镉离子的结合能力。第三代PAMAM柱状中空纤维膜在循环使用5次后仍保留72%的结合能力。另外当G3-HFM侵泡在CuCl2, Pb-(NO3)2, & CdCl2溶液中时，表面会析出Cu2(OH)3Cl, Pb3(CO3)2(OH)2, & CdCO3，没有经过树枝状改性的中空纤维膜不会析出晶体。威海晨源化工新材料有限公司整理自《Polyamidoamine Dendronized Hollow Fiber Membranes in the Recovery of Heavy Metal Ions》Qian Zhang, Na Wang, Libo Zhao, Tongwen Xu, and Yiyun Cheng  Shanghai Key Laboratory of Regulatory Biology, School of Life Sciences, Shanghai Key Laboratory of Magnetic Resonance, Department of Physics, East China Normal University, Shanghai, 200062, People’s Republic of China  CAS Key Laboratory of Soft Matter Chemistry, Department of Chemistry, University of Science and Technology of China, Hefei, Anhui, 230026, People’s Republic of China
