The outer shell of the crustacean, the outer skin of the arthropod, the outer shell and endoskeleton of the mollusk, and the cell walls of microorganisms such as fungi or yeast all have chitin. Generally, about 30% of the protein, calcium carbonate and chitin in the crab shell are used to remove the protein and dilute acid to remove the calcium carbonate, and then the pure chitin is obtained. The deacetylation treatment is chitosan. Chichisan is known to chelate with many heavy metal ions, such as copper, cadmium, zinc, uranium ions and the like. Moreover, chitosan itself has biodegradable properties and does not cause secondary pollution. However, the chitosan used in the prior art has reached a limit for the adsorption capacity of heavy metals. Those skilled in the art have long pondered all possible ways to improve the limits of chitosan's ability to adsorb heavy metals, such as the modification of chitosan, but have not yet achieved results. As mentioned above, there is a need in the industry for a way to improve the adsorption capacity of chitosan for heavy metal ions to improve the overall efficiency of adsorption of heavy metals by chitosan β 1^38061 [Summary of the Invention] The purpose of the present invention is to improve the adsorption capacity of chitosan for heavy metals.
