Here, artificial zeolite is a zeolite produced by hot water treatment of fly ash, which is discharged in large quantities from power plants using coal as an energy source, by adding alkali such as caustic soda, and its crystals are rich in phillipsite. It is Artificial zeolite has a function of easily exchanging alkali metal or alkaline earth metal ion-bonded in the zeolite with other cations such as heavy metal ions invading, and entering into the pores in the crystal structure of the zeolite. It also has a function of selectively adsorbing the gaseous substance. Further, the artificial zeolite is also excellent in the adsorption property for organic substances such as fats and oils, fatty acids and amines.
