摘　　要：综述了天然碳质吸附剂(carbonaceous geosorbent,CG)的分类、来源、基本性质及对典型有机污染物的吸附机制与特点,涉及的有机物污染物涵盖了多环芳烃、多氯联苯、多溴代二苯基醚、农药及抗生素等多种门类,包括极性、弱极性、非极性及离子型等多种化合物,具有较广泛的代表性。CG类物质与有机化合物间的分子间作用力(范德华力)对吸附作用有重要贡献,但这种分子间作用力会受到CG性质(如孔隙结构、特征基团等)和吸附质分子特点(如分子构型、官能团)的影响。深入了解CG对典型有机化合物的吸附机制及其影响因素对污染土壤环境风险评估和污染土壤修复具有重要意义。A review is presented of classification,sources and basic properties of natural carbonaceous geosorbents（ CG）and mechanisms and features of their sorption of typical organic pollutants. The organic pollutants discussed here include polycyclic aromatic hydrocarbons（ PAHs）,polychlorinated biphenyls（ PCBs）,polybrominated diphenyl ethers（ PBDEs）,various pesticides and antibiotics,and also a number of polar,semi-polar,non-polar（ apolar） and ionic compounds,all quite extensive in representativeness. The Van der Waals force existing between CG-type materials and organic chemicals contributes significantly to the adsorption of the latter by the former,however,the force may be affected by properties（ like pore structure,characteristic groups） of the CG material and a desorbate molecular characteristics（ like molecular structure,functional groups）. Insight into mechanisms of CG adsorbing these typical organic compounds and their affecting factors will be of great significance to environmental risk assessment and remediation of contaminated soils and groudwater.
