摘　　要：蒙脱石(Montmorillonite)因其具有较大的比表面积、丰富的孔结构及低廉的成本,在众多领域广泛应用。尤其在工业废水处理领域,与传统的吸附剂相比,蒙脱石因其特殊的结构,可以通过无机改性来改善其孔结构、提高其比表面积,从而提高其吸附容量;通过有机改性来改善其表面疏水性,增加对有机分子间的亲和力,为拓展蒙脱石在工业废水处理领域中的应用提供了新思路。本文阐述了蒙脱石的结构、性质以及改性方法,在此基础上,着重归纳了无机-有机柱撑蒙脱石在工业废水处理中的应用研究状况,并对研究前景进行了展望。Due to its larger specific surface area,abundant pore structure and low cost,montmorillonite has been used in many fields,especially,industrial wastewater treatment. Therefore,based on the special structure of montmorillonite,the inorganic modification is proposed to improve its adsorption capacity by promoting its pore structure and surface area,compared with the traditional adsorbent.However,in order to further raise the adsorption capacity,it is an innovative idea that the organic modification was adopted to reduce its surface hydrophobicity and increase the addinity between the organic molecules. The structure, properties and the modification methods of montmorillonite are explained in this paper. In addition,inorganic-organic pillared of montmorillonite in industrial wastewater treatment are mainly summarized and the application prospects of inorganic-organic pillared of montmorillonite are discussed.
