摘要
壳聚糖来源丰富,自然储量大,分子结构中存在大量的氨基、羟基等官能团,对染料废水有很好的去除效果.改性所得的壳聚糖衍生复合吸附材料,在工业废水中的稳定性、机械强度、吸附性、分离再生性都有很大的增强.综述了壳聚糖的改性及对阴/阳离子染料吸附的国内外研究进展.
Abstract
Chitosan has abundant sources,large natural reserves,and a large number of amino,hydroxyl and other functional groups in the molecular structure,which has a good removal effect on dye wastewater.The stability,mechanical strength,adsorbability,separation and regeneration of the modified chitosan derived composite adsorption materials in industrial wastewater have been greatly enhanced.In this paper,the research progress of modification of chitosan and adsorption of cationic dyes at home and abroad was reviewed.
