Abstract本发明公开了一种有机修饰纳米钛柱撑粘土及其制备方法,该方法是将膨润土与水配制成悬浮混合体系;按摩尔比表面活性剂∶阳离子交换容量=0.25~6∶1的比例加入表面活性剂进行恒温离子交换反应,然后按摩尔比钛离子∶阳离子交换容量=10~80∶1的比例滴加钛溶胶;钛溶胶充分沉淀后,离心水洗;将水洗后的沉淀物干燥烧结,研磨过筛后,获得所述有机修饰纳米钛柱撑粘土。本发明制备的柱撑粘土对疏水性有机污染物具有较强的吸附性能,又具有较强的光催化活性,克服了单纯的有机、无机钛柱撑粘土只能单方面吸附或者降解污染物的缺点,并同时使材料能够再生,解决了后处置问题。本发明采用的原料来源广泛,经济实用,可二次回收利用。
