Abstract: With the continuous development of industry, heavy metal pollution is deepening day by day, which seriously endangers human health. In recent years, chemically modified zeolite has been widely used in the field of heavy metal ions treatment because of its large specific surface area and strong ion exchange capacity. However, due to the use of acid, alkali, inorganic salts and organic reagents as modifiers in the chemical modification process, there are still some drawbacks in terms of energy consumption, cost and sustainable development. Therefore, it is of great significance and economic benefit to carry out the research on chemical modification methods of zeolite to make it simple, industrialized and green. In this paper, the methods of chemically modified zeolite were introduced from the structure level of zeolite, the excellent properties of magnetic zeolite and nanometer zeolite were analyzed, the application of modified zeolite in removing heavy metal ions was summarized, and the future development trend of the modified zeolite was prospected.

Key words: chemical modification, zeolite, magnetism, nanocrystallization, heavy metal ion, adsorption
