摘要
为了提高膨润土吸附金属阳离子能力，本文进行了硅溶肢改变膨润土端面电荷性质研究，研究了硅溶胶调变膨润土端面正电量影响因素。试验证明硅溶胶能使膨润土端面荷正电，用硅溶胶改性的膨润土吸附阳离子能力有很大提高。
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.
