摘要
生物炭(Biochar)是动植物材料经厌氧限温裂解制备而成的一种碳含量丰富的稳定性多孔炭。由于其丰富的孔隙结构和独特的表面化学性质而具有良好的吸附性,且廉价易加工,被广泛应用于废水重金属处理中。本文对生物炭的概念、基本特性、生物炭吸附废水中重金属的机理与影响吸附的因素等进行了综述,并探讨了生物炭在重金属废水处理中未来的研究方向。
Biochar is a stable carbon-rich product synthesized through pyrolysis/carbonization of plant- and animal-based biomass. Due to its abundant pore structure, unique chemical properties, adsorption capacities, cheap cost and easy processing, biochar has been widely applied to heavy-metal wastewater treatment. This review focused on the concept and properties of biochar, mechanisms and affecting factors of biochar interactions with metals and discussed the future research direction in waste water treatment.
