[0024]Mix and stir acrylamide, N,N-methylenebisacrylamide and tert-butanol for 10 minutes at a mass ratio of 2:1:3 to obtain a mixture, mix the mixture with deionized water at a mass ratio of 1:3 and place In the beaker, continue to stir for 11 minutes to obtain a self-made mixture; weigh 10g of citrus and 16g of spinach and mix them in a blender for 16 minutes to obtain a crushed product. Mix the crushed product with distilled water at a mass ratio of 1:5 and put Put the beaker into a beaker, place the beaker in an ultrasonic oscillator, conduct ultrasonic extraction for 45 minutes at a temperature of 60°C and a power of 180W, filter after extraction, collect the filtrate, and distill the filtrate under reduced pressure to obtain a self-made plant extract. Finally, mix the self-made plant extract with the above-mentioned self-made mixed solution at a volume ratio of 1:1, and ultrasonically treat it with a power of 200W for 10 minutes, let it stand for layers, separate and remo...
