摘要:

生物炭是生物质在限氧或隔绝氧气条件下通过热解方式经化学转化而产生的一种高度芳香化固体碳质,具有易制备、应用范围广的优点。为提高原始生物炭的吸附性能和催化效能,众多研究者对其进行了改性。基于此,综述了生物炭的化学改性策略,包括元素掺杂改性、酸/碱改性、氧化/还原改性以及金属盐/氧化物改性等,并分析了改性策略改善生物炭物理化学性能的机制,在此基础上,阐述了经化学改性后的生物炭在去除水体中有机污染物和无机污染物方面的应用,最后,提出了化学改性生物炭去除水中污染物的未来探索方向。

Abstract:

Biochar is highly aromatic solid carbons produced by chemical transformation of biomass through pyrolysis under oxygen limited or oxygen isolated conditions. It has the advantages of easy preparation and wide application range. To improve the adsorption performance and catalytic efficiency of raw biochar, numerous studies had conducted to modify it. Based on this, the chemical modification strategies of biochar were summarized, including element doping modification, acid/base modification, oxidation/reduction modification, and metal salt/oxide modification. The mechanism of improving the physical and chemical properties of biochar by modification strategies was analyzed. On this basis, the application of chemically modified biochar in removing organic and inorganic pollutants from water was elaborated. Finally, the future exploration directions of chemically modified biochar in removing pollutants from water were proposed.

Key words: biochar, chemical modification, adsorption, practical application
