Zeolite is a general term for zeolitic minerals. It is a kind of aluminum silicate mineral of water-bearing metal or earth metal. Its appearance is green, white or brick red. It is a weak cationic cation exchanger. Through artificial active introduction of the active components, the zeolite has a new ion exchange or adsorption capacity, the corresponding increase in adsorption capacity. The zeolites are divided into four types according to the characteristics of the minerals: scaffold, lamellar, fibrous and unclassified. They are divided into one-dimensional, two-dimensional and three-dimensional systems according to the characteristics of the pore system.
