| Abstract: | In order to improve the adsorptive power of bentonite for metal ions we studied thechanges in the charge of bentonite crystal edges witk silicic sol. The effect of the preparationconditions of silicic sol on changes in the charge of bentonite crystal edges was investigated.The experimental results indicated that the addition of silicic sol caused bentonite crystaledges positively charged,and modified bentonite possessed better adsorptive power than thoseunmodified. |
