We consider that this positive charged montmorillonite has a characteristic adsorption on Al3+ and has no characteristic adsorption on Mg2+. The interaction between it's suspension and various valence anions is in agreement with Schulze-Hardy rule. 发现该阳离子膨润土的悬浮体与不同价数的阴离子作用符合Schulze-Hardy规则,并对Al~(3+)有特性吸附,而对Mg~(2+)则没有。
