摘要
生物炭的低吸附容量和易饱和是影响其进一步应用的主要缺陷,因此,本研究通过提出一种以多孔生物炭为生物质载体,壳聚糖负载在其表面的新型高性能复合材料。该材料有效结合了生物炭疏松多孔结构和壳聚糖丰富表面官能团的优点,极大地提高了其吸附性能,其在土壤改良、水质净化等农业环境领域具有潜在的应用价值,体现“以废治废”的理念。通过介绍壳聚糖改性生物炭的制备、特性和吸附机理,并对其在土壤和水环境污染的修复、农作物生长的影响等方面的应用进行综述和总结,为壳聚糖改性生物炭进一步在环境修复中的应用提供理论支持。
The low adsorption capacity and easy saturation of biochar are the main drawbacks for its further application.Therefore,a new high-performance composite material with porous biochar as the biomass carrier and with chitosan loaded on its surface was proposed.The material has potential applications in agro-environmental fields such as soil improvement,water purification,as the material effectively combines the loose porous structure of biochar with the rich surface functional groups of chitosan,which greatly improves its adsorption performance and realizes the concept of“treating waste with waste.”The preparation,characteristics and adsorption mechanism of chitosan-modified biochar were introduced,meanwhile its applications in the remediation of soil and water pollution and its effects on crop growth were reviewed and summarized to provide theoretical support for the further application of chitosan-modified biochar in environmental remediation.
