Abstract

Abstract: Alkaline Ca-bentonite is a new kind of layered clay minerals with anion exchange performance. The preparation technology，characterization and preparation mechanism of alkaline Ca-bentonite are introduced，and the morphology，structure and behavior of raw bentonite，acid activated bentonite and alkaline Ca-bentonite are compared respectively. Furthermore，the applications of alkaline Ca-bentonite in adsorptive separation，catalytic reaction and composites preparation are also summarized. Finally，On the basis of the above analysis，the development of organic-inorganic composite wastewater treatment，solid catalyst preparation and bentonite intercalation compounds are proposed for further research of alkaline Ca-bentonite.
