Calcium montmorillonite was prepared by purifying LeXi bentonite with wet method two times. After purification, sodium modification of Ca-M was studied. A series of Fe/Cr-pillared montmorillonites were prepared with conventional method using sodium montmorillonite as experimental materials, and synthesis condition of Fe/Cr-PILM was studied and optimized. In order to shorten the preparation cycle of PILM by overleaping the step of sodium modification of Ca-M, the pretreatment technique for Ca-M has been pointed out for the first time. A series of PILMs were prepared with hydrothermal method using pretreated Ca-M as starting materials, which show that pretreatment of Ca-M is feasible.
然后,本文以莱西膨润土为原料,用二次湿法提纯了-2μm的钙基蒙脱石,对其进行了钠化改型研究;以改型后的钠基蒙脱石为原料,新型的铁、铬复合离子为柱化剂,研究并优化了常规离子交换法制备PILM的工艺;为了简化PILM的制备工艺,我们首次提出了蒙脱石的预处理工艺,希望通过预处理后可以省去蒙脱石的钠化工艺,以Ca-M为原料直接合成PILM。
