Abstract Pollution of surface water and groundwater by organic contaminants has become an increasing environmental concern. The micropores (<2.0nm) 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.
