摘要
进行了硅溶胶改变蒙脱石端面电荷性质实验。研究了硅溶胶改变蒙脱石端面电荷性质影响因素。实验结果表明：蒙脱石端面电性已经改变。改性时温度、反应时间、ｐＨ值、硅酸钠用量对改性蒙脱石吸附性有显著影响。改性后蒙脱石吸附钴离子能力提高了１０％～１７％。
Charge modification on montmorillonite edge by silica sol was performed. The effect of silica sol on charge on montmorillonite edge was investigated. The experimantal results indicate that charge on montmoril lonite edge has been changed by silica sol. In the modified process, reaction time, temperature, pH value and sodium silicate quantity have a considerable effect on adsorption of montmorillonite.Adsorption of modified montmo rillonite for cobalt ions increases by 10%～17%.
