Chitosan is the second most abundant biopolymer in nature after cellulose. It is widely distributed, mainly in the shells of many lower animals, especially arthropods such as shrimp, crabs, insects, etc., and also in lower plants. such as in the cell walls of bacteria, algae and fungi. Chitosan can be obtained by deacetylating chitin. Under the conditions of 100 °C and 40% NaOH, when chitin is acted on, a deacetylation reaction occurs to obtain chitosan. This is a white or off-white translucent flaky solid, insoluble in water and alkalis, but soluble in most dilute acids, including formic acid, acetic acid and hydrochloric acid.

1.Sewage treatment: Chitosan can treat suspended substances in sewage, adsorb certain heavy metal ions, etc., reduce BOD and COD of sewage, and chitosan can also be used in surface water treatment.
2.Petroleum Auxiliary: According to the characteristics of chitosan's macromolecule properties and amino positive charge, chitosan can also be used in the fields of petroleum exploitation and shale gas exploitation assistants.
3.Paper making: Special types of chitosan can be used as sizing agent, reinforcing agent, retention aid, etc. in paper making to increase paper strength and recover lost pulp.
4.Agriculture: Chitosan can be used in seed soaking, coating agent, foliar spray fertilizer, bacteriostatic agent, soil conditioner, feed additive, fruit and vegetable preservative, etc.
5.Chitosan is also widely used in other fields.
