摘  要:
磁性生物炭(Magnetic biochar,MBC)因其磁分离能力和广阔应用前景而受到研究者广泛关注.MBC中碳基结构特征(如形貌、比表面积、官能团等)和铁氧化物形态及分布受多因素影响,如原料来源、热解温度、合成方法等.然而,MBC特性与合成条件的关联性以及MBC对重金属的吸附机制有待进一步研究.本文通过阐述合成条件对MBC特性的影响及其吸附重金属机制,提出关于未来MBC吸附重金属研究的一些科学问题,这将为认识MBC的环境效应提供重要的基础信息.

摘  要:
Magnetic biochar(MBC)has garnered considerable research attention due to its magnetic separation capabilities and wide range of applications.The properties of MBC,such as carbon-based structural characteristics(e.g.,morphology,specific surface area,functional groups,etc.),as well as the morphology and properties of iron oxide within MBC,are influenced by various factors including raw material source,pyrolysis temperature,and synthesis methods.However,further investigation is needed to establish the relationship between MBC properties and synthesis conditions,as well as to understand the mechanism of heavy metal adsorption by MBC.This study aims to describe the impact of synthesis conditions on the characteristics of MBC and its adsorption mechanism for heavy metals.Moreover,scientific questions pertaining to heavy metal adsorption by MBC are raised,which will contribute to a better understanding of MBC persistence.
