[0002] Bentonite is a non-metallic mineral with montmorillonite as its main mineral component. The montmorillonite structure is a 2:1 crystal structure consisting of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedron. Due to the presence of certain cations such as Cu, Mg, Na, K, etc. in the layered structure formed by the montmorillonite unit cell, and the unstable interaction between these cations and the montmorillonite unit cell, which can be easily exchanged by other cations, it has good ion exchangeability. Therefore, the demand for bentonite is growing.
