细菌纤维素制备及吸附金属离子的研究进展

Advance in Research on Preparation and Adsorption of Metal Ions of Bacterial Cellulose

摘要:

细菌纤维素（BC）是一种由微生物发酵制备的纤维素，具有独特的结构和物理化学性质。BC分子存在大量的羟基，具有超细网状纳米纤维结构，比表面积高，对溶液中金属离子有良好的吸附性能。本文对细菌纤维素制备条件（菌种、常用碳源及助剂）、细菌纤维素吸附重金属离子及机理的研究进展进行了总结及展望。

Abstract:

Bacterial cellulose (BC) is a kind of cellulose produced through microbial fermentation, which has a unique structure and physiochemical properties. BC has a lot of hydroxyl groups, ultra-fine fiber network, and high specific surface area, which enable BC have good adsorption properties to the metal ions in aqueous solution. The preparation conditions (including bacteria, carbon sources, additives) of BC are reviewed. The adsorption and the adsorption mechanism of heavy metal ions on BC are also reviewed and outlooked.
