生物炭去除邻苯二甲酸酯的研究进展

Research progress on the removal of phthalates from biochar

生物炭由于其良好的孔隙结构以及表面负载的官能团,被广大学者用以处理邻苯二甲酸酯污染修复问题。近年来,学者发现由生物质直接制备的生物炭的吸附效果较为有限,因而开始采用化学、物理等方法对生物炭的性能进行改良。综述了不同来源的生物质制备的生物炭性质上的差异以及目前的新型制备方法对生物炭性质的优化;阐述了生物炭吸附过程中主要涉及的吸附机理,以及影响因素;并指出了今后研究可以根据吸附机理以及影响因素等考虑如何制备吸附性能更优秀的生物炭,目前生物炭吸附PAEs存在的一些问题以及今后的工作。

Due to its good pore structure and surface loaded functional groups,biochar has been used by many scholars to treat the remediation of phthalate pollution.In recent years,scholars have found that the adsorption effect of biochar prepared directly from biomass is relatively limited,and therefore,chemical and physical methods have been used to improve the performance of biochar.The differences in the properties of biochar prepared from different biomass sources and the optimization of biochar properties by the current novel preparation methods are reviewed;the adsorption mechanism and influencing factors involved in the biochar adsorption process are elaborated;and it is pointed out that future research can consider how to prepare biochar with better adsorption performance based on the adsorption mechanism and influencing factors,some issues and future work.
