【摘要】 离子交换和多孔材料是一类高效的吸附剂,这类新型的高效吸附分离材料具有高的比表面积或丰富的表面官能团;显示出高的吸附容量、快的吸附或脱附速度和一定的吸附选择性;可织成束、纸、布、毡等多种集合形态.本文简要地介绍了包括离子交换纤维、螯合纤维、活性碳纤维、碳气凝胶等新型离子交换和多孔材料的制备、吸附特征研究的进展,并介绍了它们在饮用水净化、环境治理、资源回收、化学工业和医疗卫生、催化剂等方面的应用.更多还原

【Abstract】 Ion exchange and porous materials are high effective adsorbents.These novel adsorbents have high specific surface areas or abundant functional groups,which make them have greater adsorption/desorption rate and larger adsorption capacity than other adsorbents.Besides granules or fibers,they can also be prepared as bundle,paper,cloth and felt to meet various technical requirements.In this paper the latest progress in the studies of author’s group on the preparation and adsorption properties of these novel adsorbents such as ion exchange fibers,chelating fibers,activated carbon fibers,and carbon aerogels is reviewed.The applications of these materials in drinking water purification,environmental control,resource recovery,chemical industry,medicine and health care and in preparation of catalyst are also presented.更多还原
