摘　　要：近年来,以甘蔗渣为原料制备的生物炭,因具有来源广、成本低、制备方法简单和吸附能力强等优点受到研究者的广泛关注,常作为钝化剂用于重金属污染的土壤修复。然而,以往研究人员对生物炭的关注多集中在常规尺寸上效应,缺乏对其微米或纳米尺寸上的研究。近期有研究表明,原始生物炭和纳米生物炭的理化性质有显著差异。在农业和环境领域,与原始生物炭相比,通过低能耗、强操作性和绿色环保的物理改性方法制备的纳米生物炭具有更强的性能。本文主要讨论了纳米生物炭材料在环境保护领域的应用,具有重要的理论和实践指导意义。In recent years,Biochar derived from sugarcane bagasse,owing to its advantages such as widespread availability,low cost,simple preparation methods,and strong adsorption capacity,has received extensive attention from researchers.It is commonly used as a passivating agent for the remediation of heavy metal-contaminated soils.However,previous research has predominantly focused on the effects of biochar at conventional sizes,lacking investigation into its properties at the micron or nanoscale.Recent studies have demonstrated significant differences in the physicochemical properties between raw biochar and nano biochar.In the fields of agriculture and the environment,nano biochar,prepared through low-energy,highly manipulable,and environmentally friendly physical modification methods,exhibits superior performance compared to raw biochar.This article primarily discusses the application of nano biochar materials in the field of environmental protection,holding significant theoretical and practical guidance value.
