摘要
随着经济的快速发展,水中重金属离子污染对人类健康以及生态系统造成威胁.水凝胶以其良好的吸附性能、可再生性和低毒性在处理重金属离子方面具有很大的潜力.本文论述了近年来国内外以农业固体废弃物为原料制备水凝胶(纤维素基水凝胶、半纤维素基水凝胶、木质素基水凝胶等)吸附重金属的研究进展.同时,讨论了农业固废基水凝胶的合成,对重金属的吸附效果、吸附机制及分析方法,并列举了工业固废基和其他固废基水凝胶吸附重金属的效果,以期帮助研究者对农业固废基水凝胶吸附重金属的探究有更深刻的理解.
Abstract
With the rapid development of economy,the pollution of heavy metal ions in water poses a threat to human health and ecosystem.Hydrogels have great potential in the treatment of heavy metal ions because of their good adsorption properties,renewability and low toxicity.This paper discusses the research progress in recent years on the preparation of hydrogels(cellulose-based hydrogels,hemicellulose-based hydrogels,lignin-based hydrogels,etc.)for the adsorption of heavy metals from agricultural solid wastes at home and abroad.The synthesis of agricultural solid waste based hydrogels,the adsorption effect,adsorption mechanism,and analytical methods for the removal of heavy metals are also discussed,and the effects of heavy metal adsorption by industrial solid waste based and other solid waste based hydrogels are enumerated.In order to help the researchers to have a deeper understanding of the investigation of heavy metal adsorption by agricultural solid waste based hydrogels.
