Embodiment 1
[0020] Choose mature and tall peanut straw, soak it in tap water, wash it to remove soil and dust, wash it with distilled water, and dry it to constant weight at 80°C; grind the dried peanut straw into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 50 g of the obtained powder and soak it in deionized water, add 2 mL each of the activated 0.01 mol / L amylase solution and protease solution, react at 35-50 °C for 1 hour, and then add 10mL of 0.05mol / L KOH solution, react for 50 minutes, and then use H 2 SO 4 Neutralize the solution, filter the neutralized liquid, and then dry it; mix the dried powder and urea in a mass ratio of 1:1, then re-immerse in deionized water, react at 50°C for 6 hours, filter, Afterwards, wash with deionized water three times to remove residual ionic liquid, and then wash with 95% alcohol twice, after washing, put it into an electric heating constant temperature drying oven at 50°C to dry to obtain the peanut straw adsorptio...

[0022] Choose mature and tall peanut straw, soak it in tap water, wash it to remove soil and dust, wash it with distilled water, and dry it to constant weight at 80°C; grind the dried peanut straw into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 50 g of the obtained powder and soak it in deionized water, add 2 mL each of the activated 0.05 mol / L amylase solution and protease solution, react at 35-50 ° C for 2 hours, and then add 10mL of 0.1mol / L KOH solution, react for 50 minutes, and then use H 2 SO 4 Solution neutralization. Filter the neutralized liquid and dry it in the air; mix the dried powder and urea in a mass ratio of 1:1, then re-immerse in deionized water, react at 50°C for 8 hours, filter, and then use deionized Wash with water for 3 times to remove residual ionic liquid, and then wash with 95% alcohol for 2 times. After washing, put it into an electric heating constant temperature drying oven at 50°C to dry to obtain the peanut s...
Embodiment 3
[0024] Choose mature and tall peanut straw, soak it in tap water, wash it to remove soil and dust, wash it with distilled water, and dry it to constant weight at 80°C; grind the dried peanut straw into powder, and select Pass through a 60-mesh sieve to collect the powder; weigh 100 kg of the resulting powder and put it into a 3-ton sanitary storage tank, and inject an appropriate amount of deionized water into the tank, add 2 mL each of the activated 0.05mol / L amylase solution and protease solution, and React at 50°C for 2 hours, then add 5L of 0.1mol / L KOH solution, react for 1 hour, and then use H 2 SO 4 Neutralize the solution, filter the neutralized liquid with a plate-and-frame compressor, and then dry it; mix the dried powder and urea in a mass ratio of 1:1, put it into a 3-ton sanitary tank, and inject it into a deionized tank water, kept at 50°C for 8 hours, filtered, washed with deionized water 4 times to remove residual ionic liquid, and dried at 50°C after washing ...
