Bentonite is a non-metallic mineral with montmorillonite as its main mineral component.
The structure of montmorillonite is a 2:1 crystal structure composed of two silica tetrahedrons sandwiched with a layer of aluminum oxide octahedrons. The layered structure formed by montmorillonite cells contains some cations, such as Cu, Mg, Na, K, etc., and the interaction between these cations and montmorillonite cells is very unstable and easy to be exchanged by other cations, so it has good ion exchange property.
