摘　　要：以几种来源不同的蒙脱土为原料,在柱撑了羟基铝之后,用比表面积分析(BET)法、红外光谱(IR)法、X射线衍射(XDR)法等对柱撑后的蒙脱土进行了表征。结果表明,制备出的柱撑蒙脱土与原蒙脱土相比,比表面积、层间距都明显增大,但柱撑后的蒙脱土碳含量明显降低。This paper introduces some montmorillonite of different production technologies. Montmorillonite and pillared agents are used to synthesize the pillared montmorillonite. The pillared montmorillonite was identified by BET, IR and XDR. The result shows of pillared montmorillonite that compared with the original montmorillonite, its specific surface area and basal interlayer space are greatly increased,but its content of carbon is greatly reduced.
