Constant/permanent charge


Constant/permanent charge is mainly generated by isomorphic substitution and does not change with the change of pH and electrolyte concentration.

Variable charge


Variable charge can be generated through dissociation of functional groups and varies with pH value, the properties of colloid surface and ionic concentration.
