The adsorption effect of montmorillonite includes surface adsorption and ion exchange adsorption, but its adsorption effect on non-ionic organic pollutants depends on the size of organic cations, and also depends on the cation exchange capacity of different montmorillonites, so the effect is relatively unstable.

Zeolite is a water-bearing alkali metal or alkaline earth metal silica-aluminate mineral, which is a tetrahedron composed of three elements: silicon (Si), aluminum (Al), and oxygen (O), among which the silicon and oxygen tetrahedra and the aluminum-oxygen tetrahedra form an infinitely expanding thre

Petroleum and chemical industry Zeolites can be used as catalysts and their carriers. Catalysts with zeolites as the basic raw material are used in a wide range of applications, mainly in the following fields. Used as cracking catalyst, hydraulic catalyst and hydrocracking in petroleum refining proc

Air purification materials Zeolite, as a porous mineral material with microporous pore and void structure and ion exchange and adsorption selectivity, can be a medium for nano-scale unitary substances to arrange and generate assembled materials in one-dimensional, two-dimensional and three-dimensio
