气凝胶材料在染料废水处理领域的研究进展

Review of Aerogels Technology in the Field of Dye Wastewater Treatment

气凝胶是一种具有高比表面积、高孔隙率、超低密度的三维纳米多孔网络结构材料,因其优异的物理特性在诸多领域均有广阔的应用前景。纺织行业的快速发展带来了一系列的水污染问题,染料废水成分复杂、处理难度高,引发了研究者的极大关注。文中主要介绍了气凝胶材料在染料废水处理方面的研究,对其处理机理进行了总结,分析了气凝胶材料在处理染料废水领域的优势,并对今后气凝胶材料在该方向的发展进行了展望。

Aerogels,which have a three-dimension nanoporous network,due to their high porosity,high specific surface and ultralow density,possess extensive potential applications on many fields.The rapid development of the textile industry has brought about a series of water pollution problems.And the composition of organic dyes is complex and hard to deal with which has attracted the attention of researchers.This paper introduces the research and summarizes the treatment mechanisms of aerogels for eliminating organic dyes from water,and also compares the advantages of aerogels and other various materials.In the end,the outlook for future development of the aerogels in dyes removal from water is prospected.
