多孔材料在去除废水中重金属离子方面的研究进展

Research progress of porous material applied in removing heavy metal ions from wastewater

多孔材料是一种具有一定尺寸空隙结构和具有一定比表面积的材料,按其孔径大小可分为微孔材料、介孔材料和大孔材料。多孔材料具有相对密度小、比表面积高、重量轻、渗透性好等特点,并具有很好的吸附性能。本文主要重点介绍了几种不同的多孔材料作为吸附剂应用于去除废水中的重金属离子。

Porous material is a kind of material with a certain size of the gap structure and a certain specific surface area,according to the size of its pore size can be divided into microporous materials,mesoporous materials and macroporous materials.Porous materials with a relative density,high specific surface area,light weight,good permeability and good adsorption properties.The use of porous materials as adsorbents for the removal of heavy metal ions in wastewater was focused.
