Influence of mineralogical and morphological properties on the cation exchange behavior of dioctahedral smectites

- Dioctahedral smectites display structural heterogeneities and variation in size.
- Wyoming smectite is significantly different from other dioctahedral smectites.
- CEC increases with pH similar for natural and reduced charge montmorillonites (RCM).
- RCM are suitable to study edge surface properties of montmorillonites.
