Embodiment 1
[0038] (1) After cleaning the sycamore flocs and the ground peanut shells for 3 times with deionized water, soak them in 30wt% hydrochloric acid for 10 hours, then wash them with ionized water until they are neutral, and finally dry them at 80°C for later use;
[0039] (2) Take 4g of paraffin and 0.56g of Span 80 (span~80), put them into a water bath at 70°C and heat until the paraffin is completely dissolved into a colorless and transparent liquid to obtain molten paraffin; take 15g of glucose and 23.5ml of deionized water Stir with Tween 80 (Tween~80) 1.44g evenly and put it into a 70°C water bath to heat to obtain an aqueous glucose solution, then slowly add the aqueous glucose solution to the molten paraffin and stir evenly, then add the treated 1g sycamore floc, 2g peanut shells, then add 0.05g nickel hydroxide and ultrasonically stir at 70°C for 1h, then add gelling agent (acrylamide 4.5g and methylenebisacrylamide 0.5g) and catalyst (ammonium persulfate 1g) to prepare a...
