摘要
综述了磁性生物炭的制备原料、方法,并比较了各方法的优缺点,分析了静电吸附、沉淀与共沉淀作用、π-π电子相互作用和疏水作用吸附机理,最后探讨了吸附污染物的影响因素。在此基础上提出了未来磁性生物炭的发展方向,以期为磁性生物炭在污染治理领域提供理论依据。
This account reviews the raw materials and methods for preparation of magnetic biochar,compares the advantages and disadvantages of various methods,and analyzes the adsorption mechanism,including electrostatic adsorption,precipitation and co-precipitation,π-πelectron interaction,and hydrophobic interaction.Finally,the factors affecting the adsorption of pollutants by magnetic biochar are expounded.On this basis,the development directions of magnetic biochar in the future are proposed,aiming to provide theoretical guidance for the application of magnetic biochar in pollution control.
