The invention discloses a cellulose-doped chitin hydrogel and a preparation method thereof. The preparation method is as follows: firstly, the chitin is subjected to alkali-acid-base pretreatment, and then the pretreated chitin and cellulose are added to a mixture of NaOH and urea. After dissolving in the aqueous solution, freeze and thaw, and then add epichlorohydrin to carry out chemical cross-linking reaction. The obtained cellulose-doped chitin hydrogel not only has good adsorption performance, high mechanical strength, and good cycle performance, but also has the advantages of The cost of raw materials is low, the preparation method is simple, and it is suitable for popularization and application. |
