摘　　要：磷是水体富营养化的重要限制因子。生物炭具有高比表面积、高孔容积和表面含有丰富的官能团等特点,可以用于吸附除磷,具有低成本、效率高等优势,而被广泛应用,但由于原生物炭对磷的吸附能力有限,有必要对其进行改性。本文分析了近年来生物炭的改性方法和吸附机理,生物炭改性方法有球磨法、化学法和微生物法等,化学法主要有酸碱、金属、非金属、矿物质和有机物改性。吸附机理主要有静电吸引、离子交换、化学沉淀和配体交换等,进而为实际利用生物炭吸附水中的磷提供一定理论依据。Phosphate is an important limiting factor of water eutrophication.Biochar presents the advantages of large specific surface area,high porosity volume and abundant surface functional groups.Biochar has been widely used as an adsorption material with high performance in phosphate removal based on biochar with the advantages of low cost,high effect.The phosphate adsorption capacity of pristine biochar is limited.It is necessary that the biochar was modified.In this paper,the various methods of biochar modification and adsorption mechanism were analyzed in recent years.The modification methods of biochar included ball-milling,chemical modification and microbiological modification.Chemical agents(acid/base,metal salts,non-metal compound,mineral and organic compounds)were employed in biochar modified by chemical methods.The adsorption mechanisms included electrostatic attraction,ion exchange,chemical precipitation,and ligand exchange.The mentioned methods and mechanisms can be used as a theoretical basis for the practical use of biochar.
