摘要
水资源是人类生存不可或缺的要素,水质净化处理已成为亟待解决的问题。文章综述近年来生物质基水凝胶吸附水中污染物(如重金属离子、染料等)的研究进展,详细阐述了纤维素基、壳聚糖基、海藻酸钠基、半纤维素基及其他生物质基水凝胶对水环境中染料及重金属(Cr、Pb、Ni、Cu)的吸附机理。最后,针对聚合物凝胶净化水环境研究中存在的问题提出建议,并对未来发展方向进行探讨。
Water resources are an essential element for human survival,and water purification has become an urgent issue to address.The article reviewed the research progress of biomass-based hydrogels in adsorbing water pollutants(such as heavy metal ions and dyes)in recent years.It elaborated on the adsorption mechanisms of cellulose-based,chitosan-based,sodium alginate-based,hemicellulose-based,and other biomass-based hydrogels for dyes and heavy metals(Cr,Pb,Ni,Cu)in the aquatic environment.Finally,it put forward suggestions for the existing problems in the research of polymer gels in purifying the water environment and discussed the future development directions.
