摘要
The effects of saturating cation (Na or K) and pH on the critical coagulation concentrations (CCCs) of illite were measured. Increasing CCC with increasing pH was explained by charge alterations on the edge surfaces due to surface-specific proton interactions. A comparison of our Na-illite CCCs to published Na-kaolinite and Na-montmorillonite CCCs revealed a greater pH dependence for Na-illite and Na-kaolinite CCCs. -from Authors
