摘　　要：生物质炭是近年来新兴的一种碳质吸附剂,具有优良的结构、物理化学性质和生物相容性,并且制备工艺简单、原料来源广泛且廉价可再生,成为污水处理领域研究的热点材料。掺杂改性能够优化生物质炭的比表面积、孔结构、电负性以及表面官能团种类和数量,是提高其吸附性能的有效策略。综述了污水处理生物质炭吸附剂的掺杂策略(金属掺杂、非金属掺杂和共掺杂)及其制备方法和吸附机理,分析了其目前存在的问题及未来的研究方向。Biochar,an emerging type of carbonaceous adsorbent in recent years,has been regarded as a hot research material in the field of wastewater treatment because of its excellent structure,physicochemical properties and biocompatibility as well as simple preparation process,widely sourced and inexpensive renewable raw materials.Doping can optimize the specific surface area,pore structure,electronegativity and the types/quantities of surface functional groups of biochar,which is an effective strategy to improve its adsorption performance.The doping strategies(metal doping,non-metal doping and co-doping),preparation methods and adsorption mechanism of biochar adsorbents for wastewater treatment are reviewed.The current problems and future research directions are analyzed.
