摘　　要：粘土矿物作为良好的天然吸附材料,在环境污染治理中有着广泛的应用前景,但多数粘土矿物含有杂质,存在理化构造缺陷,这些限制了其吸附性能的发挥,柱撑改性能都很好地解决这一问题。本研究从柱撑粘土矿物的制备及其对环境污染物的吸附着手,系统综述了柱撑粘土矿物的制备工艺、制备机理和柱撑粘土矿物对污染物的吸附性能、吸附条件、吸附机制,为粘土矿物的应用与研究提供较为详尽的资料。As a kind of effective natural adsorption material, clay mineral has a broad application prospects in environmental pollution control. However, most kinds of clay contain impurities, and their physicochemical structure has defects, restricting their adsorption performance. Pillared clay modification is an effective solution to this problem. By commencing from preparation process of pillared clay and its adsorption on environmental pollutants, the pillared clay preparation process and mechanism, as well as the adsorption property of the pillared modified clay to pollutants, adsorption condition and adsorption mechanism of pillared clay were systematically summarized, thus providing detailed information for extending research and application of clay mineral.
