摘要:

近年来,三维网络水凝胶由于具有较高的吸附容量、较快的吸附速率和较好的再生性能,在废水处理方面受到了人们的广泛关注。本文简单介绍了三维网络水凝胶,重点评述了在重金属离子和染料废水方面的研究进展,并探讨了三维网络水凝胶吸附处理中存在的问题,展望了今后重点研究的方向。

Abstract:

In recent yearshydrogels have attracted a great deal of attention due to their high adsorption capacityfast adsorption rate and good regeneration properties. The hydrogels with three-dimensional cross-linked polymeric networks are briefly reviewed in this paper. Their adsorption properties of heavy metal ions and dyes are emphatically summarized. Problems of adsorption in wastewater treatment are addressed. The potential research areas are also prospected.
