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.
