中文摘要：

制备了对水体中的砷具有良好吸附效果的柱撑蒙脱土。研究了在紫外光照射的强化作用下的除砷效果，并确定了适宜的吸附砷工艺条件。结果表明经过压力溶弹处理的钛柱撑蒙脱土，Ti元素有效地替换了蒙脱土层间的Al元素，形成锐钛矿型TiO2柱撑结构，晶型发育比较完全，可以有效地去除水体中的砷。

英文摘要：

An adsorbent Ti-pillared montmorillonite（Ti-PILC） with high efficiency to remove arsenic in water was prepared. The effect on removing arsenic under ultraviolet light irradiation has been analyzed and suitable conditions of preparation have been found. The results indicate that Ti-PILC which was disposed at certain temperature and pressure for hours can better remove arsenic in water than the others, and the aluminum in the interval of Na-montmorillonite（Na-MMT） has been replaced by titanium effectively, during which anatase-TiO2 is completely built and the structure of Ti-pillared is formed.
