有机污染物对地表和地下水环境的污染是当前环境保护领域的重要问题之一。矿物的微孔结构(<2.0 nm)对有机污染物在地下水环境中的长期迁移与归宿以及吸附处理污染水体方面具有重要的意义和应用价值。本文在介绍矿物微孔吸附机理的基础上,探讨了矿物孔道的表面化学性质,有机污染物本身的物理化学性质,以及水环境中的共存溶解性有机质和金属离子对有机污染物在矿物微孔中吸附的影响。 |

Pollution of surface water and groundwater by organic contaminants has become an increasing environmental concern. The micropores (<2.0 nm) of minerals can play an important role in controlling the long-term transport and fate of organic contaminants in groundwater aquifers,and can be potentially applied in sorptive removal of organic contaminants from polluted water. This paper gives an overview on the mechanism of organic contaminant sorption in mineral micropores and discusses the major factors controlling the sorption process,including surface chemistry of the pore wall,physical and chemical properties of the organic contaminants,and dissolved organic matter and metal ions in the aquatic environment. |
