Embodiment 1
[0042] Example 1: The peanut shell biochar composite hydrogel provided in this example, the composite hydrogel includes peanut shell biochar (B), acrylamide (AM), carboxymethyl cellulose (CMC), ammonium persulfate (APS) and N,N'-methylenebisacrylamide (MBA), where peanut shell biochar: carboxymethyl cellulose: acrylamide = 4:1:8, where the mass of ammonium persulfate is acrylamide and 1% of the mass sum of carboxymethyl cellulose, and 0.5% of the mass sum of acrylamide and carboxymethyl cellulose in the mass of N,N'-methylenebisacrylamide.
[0043] Preparation:
[0044] The first step is to cut the washed and naturally air-dried peanut shells into small pieces of about 2cm and crush them through a 2mm sieve with a grinder, then put the crushed peanut shells in a muffle furnace, and pyrolyze them at 450°C for 3 hours to obtain peanut shell organisms charcoal, after the reaction, close the muffle furnace and wait for the pyrolysis gas to cool down to room temperature, take out ...
Embodiment 2
[0047]Example 2: The peanut shell biochar composite hydrogel provided in this example, the composite hydrogel includes peanut shell biochar (B), acrylamide (AM), carboxymethyl cellulose (CMC), ammonium persulfate (APS) and N,N'-methylenebisacrylamide (MBA), where peanut shell biochar: carboxymethyl cellulose: acrylamide = 3:1:6, where the mass of ammonium persulfate is acrylamide and The mass sum of carboxymethyl cellulose is 0.5%, and the mass of N,N'-methylenebisacrylamide is 0.3% of the mass sum of acrylamide and carboxymethyl cellulose.
[0048] Preparation:
[0049] The first step is to cut the washed and naturally air-dried peanut shells into small pieces of about 2cm and crush them through a 2mm sieve with a pulverizer, then put the crushed peanut shells in a muffle furnace, and pyrolyze them at 420°C for 4 hours to obtain peanut shell organisms charcoal, after the reaction, close the muffle furnace and wait for the pyrolysis gas to cool down to room temperature, take ...
Embodiment 3
[0052] Example 3: The peanut shell biochar composite hydrogel provided in this example, the composite hydrogel includes peanut shell biochar (B), acrylamide (AM), carboxymethyl cellulose (CMC), ammonium persulfate (APS) and N,N'-methylenebisacrylamide (MBA), where peanut shell biochar: carboxymethyl cellulose: acrylamide = 5:1:10, where the mass of ammonium persulfate is acrylamide and The mass sum of carboxymethyl cellulose is 1.5%, and the mass of N,N'-methylenebisacrylamide is 0.8% of the mass sum of acrylamide and carboxymethyl cellulose.
[0053] Preparation:
[0054] The first step is to cut the washed and naturally air-dried peanut shells into small pieces of about 2cm and crush them through a 2mm sieve with a grinder, then place the crushed peanut shells in a muffle furnace, and pyrolyze them at 480°C for 2 hours to obtain peanut shell organisms charcoal, after the reaction, close the muffle furnace and wait for the pyrolysis gas to cool down to room temperature, take...
