改性壳聚糖在印染废水处理中的应用研究进展

Research Progress on Application of Modified Chitosan in Treatment of Dyeing Wastewater

壳聚糖是一种可吸附水体多种污染物的天然高分子材料,已被广泛应用于废水处理的研究中,但它存在的一些缺点(如机械性能低、酸稳定性低、孔隙率低等)限制了其在水处理中的应用范围与潜力。本文综述了壳聚糖物理改性和化学改性的方法以及改性壳聚糖在印染废水处理中的应用研究进展,对壳聚糖改性的下一步研究方向做了展望。

Chitosan is a natural polymer adsorbing various pollutants in water,and it has been widely used in the research of wastewater treatment. However,the existed shortcomings,such as low mechanical properties,low acid stability,low porosity,etc.,limit the scope and potential of applications in the water processing. The methods of physical and chemical modification of chitosan were reviewed and the applications of modified chitosan in the treatment of dyeing wastewater were presented.
