| 中文摘要: |
| 生物炭含碳量高,具有较大的孔隙度和比表面积,是天然的吸附材料,其吸附性能高、成本低廉,具有改良土壤、增加碳汇、修复环境污染等功能,被广泛应用于农业、生态修复和环境保护领域。近年来,越来越多的学者开始研究生物炭复合材料的制备,将生物炭与其他材料组合,利用物理、化学方法合成具有新性能、新结构的材料,提高吸附材料的性能。通过综述生物炭及其复合材料的制备、表征方法以及其在污染治理方面的应用,阐述了生物炭及其复合材料对水体和土壤中污染物的修复机制,在此基础上提出了将来研究高效生物炭吸附材料的重点和方向,以期为生物炭的大规模应用提供参考。 |
| 英文摘要: |
| With great specific surface area, high adsorption capacity, low cost, and strong stability, biochar has been widely applied to improve soil quality, increase soil carbon sequestration, remediate polluted environment, and reduce soil emissions of greenhouse gases. Recently, efforts have been made to enhance the adsorption capacity of biochar by preparing biochar-based composites with new properties and new structure via combining biochar with other materials physico-chemically. This review summarized the preparation, characterization, and applications of biochar and biochar-based composites. The adsorption behavior and remediation mechanisms of biochar and its composites in soil and water environment were discussed in details. Key points and research directions on biochar composites were proposed. |
