[0002] Chitosan is a natural high molecular polysaccharide with positive charge that is extremely abundant in nature. It is a straight chain sugar connected by 2-acetamido-2-deoxy-D-glucose through β-(1-4) glycosidic bonds. Chitosan is the product of chitosan macromolecules after acetyl removal. Its molecular chain contains reactive groups -NH2 and -OH. It will show the properties of cationic polyelectrolytes in acidic solutions and show good flocculation properties. The crushed chitosan is suspended in isopropanol and swelled at room temperature for 1-5 hours to obtain a mixture; the first sodium hydroxide solution is added dropwise to the mixture, stirred evenly, and frozen overnight; chloroacetic acid is dissolved in isopropanol under water bath heating conditions, and added dropwise while stirring. After the addition is completed, it is kept warm in a water bath at 50°C; the supernatant is poured out, 30mL of water is added to dissolve, and suction is filtered. The filtrate is precipitated with 3 times the amount of anhydrous ethanol, and then washed with an ethanol solution with a concentration of 95%, and vacuum dried to obtain O-carboxymethyl chitosan.

[0003] In the process of producing carboxymethyl chitosan, the carboxymethyl chitosan can be better processed and handled by using a stirring device, so that the carboxymethyl chitosan can be obtained more quickly and the overall applicability during use is increased.
