改性纤维素材料对金属离子吸附研究进展

Progress Research on Adsorption of Metal Ions by Modified Cellulose Material

纤维素在地球上含量十分丰富,且表面含有大量的羟基,可以通过羟基一系列的衍生反应,对纤维素进行改性,将纤维素制成离子型的吸附剂。本文就纤维素改性,综述了近些年来国内外以纤维素为原料改性制得的吸附剂相关的研究进展。

Cellulose is one of the most abundant renewable and inexpensive natural polymers on earth,there are large amount of relatively easily accessible hydroxyl groups in the cellulose. The useful adsorbents with high adsorption capacity toward metal ions can be obtained through derivatization of hydroxyl groups in the cellulose. In this paper,the preparation and latest advances on research and applications of cellulose adsorbent were reviewed.
