Chitosan Nitrate is one salt of the biopolymer chitosan, and chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and shrimp and crab shells.
Chitosan Nitrate has wide range of new and exciting applications. It has been employed as flocculant agent for water treatment, as bactericide and fungicide in agriculture, as preservative in alimentary formulation, etc. Additionally, chitosan has demonstrated to be a promising material for biomedical applications such as controlled drug release, enzyme immobilization for biosensor preparation, gene therapy, etc
Chitosan Nitrate has more function than chitosan, it is water soluble, could be easy dissolve in water and week acid, this could help for easy use and formulation. Furthermore, Chitosan Nitrate could provide organic source nitrogen as the fertilizer.

Chitosan Nitrate molecule has amino and hydroxyl groups, dissolved in dilute acid can form a high viscosity of colloidal solutions, its aqueous solution is cationic electrolyte, has good flocculation effect. Because the chitosan nitrate contains ammonia, especially after cross-linking, the anion has good adsorption ability. Studies have shown that crosslinked chitosan nitrate gel pellets, especially those with proton, have very significant adsorption on nitrate. Chitosan nitrate is a soil conditioner, which can prevent the occurrence of crop diseases. Saturated chitosan nitrate, when used as fertilizer, can slowly release nitrate.
