随着我国工业化水平的提高,大量有机污染物进入水体,导致水环境遭受破坏。生物质炭因比表面积大、孔隙结构发达、含氧官能团丰富等特性,对水体中有机污染物表现出良好的吸附性能。综述了近年来国内外生物质炭在水体有机污染物的吸附机理、影响因素、改性方法及对不同类型污染物的吸附应用等方面的研究进展,并对未来生物质炭对水环境中有机污染物去除的发展方向进行了探讨。
With the improvement of industrialization in China,a large number of organic pollutants have entered the water,resulting in the destruction of water environment.Biochar shows good adsorption performance for organic pollutants in water due to its large specific surface area,developed pore structure and rich oxygen-containing functional groups.In this paper,the research progress of biochar adsorption mechanism,influencing factors,modification methods and adsorption application of different types of pollutants in water at home and abroad in recent years were reviewed,and the development direction of biochar for the removal of organic pollutants in water environment was discussed.
