| 摘 要： | 生物炭(biochar)是指生物质在缺氧条件下热裂解产生的一种产物.由于其精致的孔隙结构和独特的表面化学性质,对环境介质中的有机污染物有超强的吸附能力,进而影响污染物的迁移与归宿.近年来生物炭对有机污染物的吸附特性及机理研究已成为环境科学领域的研究热点之一.本文从生物炭的典型性状、吸附有机污染物的机理、影响因素以及对土壤中有机污染物生物可给性的影响等方面进行了综述,并提出生物炭吸附有机污染物未来的研究方向. |
| 关 键 词： | 生物炭 吸附 机理 有机污染物 |

| Abstract: | Biochar is produced by the pyrolysis of biomass under oxygen-limited conditions.The high specific surface area,microporousity,and charge characteristics make boichars very efficient sorbents for a range of organic contaminants,and are expected to influence the migration and bioavaiability of organic contaminants.Biochar has recently been a topic of interest globally,due to its extraordinary ability to sorb organic contaminants.Based on a brief introduction to the properties of biochar,this study mainly reviewed the sorption mechanisms of organic pollutant by biochar.In addition,several factors that influence the performance of biochar sorption were also summarized.Finally,the trends in this research field were prospected. |
| Keywords: | biochar mechanism sorption organic contaminant |
