STUDY OF CHARGE MODIFICATION ON BENTONITE EDGE

Ma Fushan Zhang Jun Zhou Guangzeng (School of Chemical Engineering and Technology,Tianjin University)  
Charge modification on bentonite edges was performed,with several kinds of carbonate,alkali and silica sol.Adsorption of modified bentonite for cobalt ions and the effects of pH value and the crystallinity of bentonite on charges on bentonite edges modified by sillca sol were inverstigated.The results indicate that the effect on charge modification by silica sol is the best and by alkali is the worst,and that the crystallinity of bentonite has a considerable effect on adsorption of the bentonite.
