[0037] (1) Dry 10 g of bagasse xylan in a constant-temperature vacuum oven at 60° C. for 24 hours to constant weight to obtain dry-based bagasse xylan.
[0038] (2) Weigh 4 g of bagasse xylan obtained in step (1) and add it into a 250 mL four-necked flask, then add 20 mL of deionized water, and fully stir at 30° C. for 25 minutes.
[0039] (3) Weigh 0.6g of ammonium persulfate and 0.48g of sodium bisulfite in a 50mL beaker in sequence, then add 20-30mL of deionized water, stir evenly to obtain an initiator solution, and set aside.
[0040] (4) Weigh 4g of AM into a 50mL beaker, then add 30mL of deionized water into the beaker, stir evenly to obtain a monomer solution, pour it into a 100mL constant pressure dropping funnel, and set aside.
[0041] (5) Add dropwise the monomer solution obtained in step (4) to the reaction system in step (2), control the temperature at 50° C., and complete the dropwise addition in 6 hours. When adding to 1 / 2 of the monomer solution volume, add 0...
