摘　　要： 本文讨论溶液中铝的水解反应及其形态区分方法。随后,阐述了土壤和粘土矿物表面铝离子的化学形态,并着重综述目前无机和有机表面对铝离子的吸附反应研究进展。此外,对土壤固相中铝离子的释放机理进行了回顾。最后,本文还对有关研究今后值得关注的问题加以分析。 Hudrolysis reactions of aluminum in solution and methods for discriminating its species were presented firstly in this paper. Next, chemical species of aluminum existing on the clay and soil surfaces was discussed. Subsequently, Adsorption of aluminum onto various inorganic and organic surfaces were documented with the emphasis on the effects of surface on the polymerization of aluminum species, followed by changes in physical and chemical properties of clay and soil after the interfacial reaction. Besides, mechanisms controlling release of aluminum form soil solid to solution were also reviewed. Finally, aspects with regard to the future research in above fields were suggested.
