高效吸附分离功能纤维及其应用

本文主要介绍几类吸附功能纤维，包括活性碳纤维、离子交换纤维、螯合纤维和氧化还原功能纤维等的研究进展。这类新型的高效吸附分离材料具有很大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；可制成束、纸、布、毡及无纺布等多种形式；某些吸附功能纤维还具有氧化还原能力。本文简要地介绍了近年来吸附分离功能纤维的制备、吸附特征研究的进展以及它们在饮用水净化、环境治理、资源回收、化学工业和医疗卫生等方面的应用

Progeress on Functional Fibers for Adsorption and Seperation

Adsorption and separation functionalfibers are fibrous adsorbents,including activated car bon fibers,ion exchange fibers, chelating fibers,redox fibers and so on. This novelfibrous adsorbents havehigh specific surface areas or abundant functionalgroups,w hich m ake them have greater adsorption/desorp tion rate and larger adsorption capacity than other adsorbents. They can be prepared as bundle,paper,clothand felt to m eet various technical requirem ent. Som e fibrous adsorbents have redox capacity. In this paperthe latest progress on the studies of the preparation and adsorption properties of fibrous adsorbents such asactivated carbon fibers,ion exchange fibers and chelating fibers is review ed. The application of these m ateri als in drinking w ater purification, environm ental control, resource recovery, chem ical industry, and inm edicine and health care is also presented.
