[0024] Take the rice husk and wash it, dry it naturally and place it in a tube-type atmosphere furnace at 125 °C for 25 min, then pass nitrogen to remove the air, control the nitrogen flow rate to 100 mL / min, and raise the temperature to 450 °C at a rate of 5 °C / min under nitrogen protection. ℃, after heat preservation and carbonization for 1 h, let it stand and cool to room temperature to obtain carbonized rice husks, weigh 45 parts of carbonized rice husks, 10 parts of sodium fluoride and 15 parts of nano-iron powder, stir and mix them, and place them in graphite In the crucible, place the graphite crucible at 1250°C under an argon atmosphere for sintering treatment for 3 hours. After the sintering is completed, stop feeding argon gas and naturally cool to 650°C. After oxidation treatment for 5 hours, naturally cool to room temperature to obtain the modified material ; In parts by weight, weigh 45 parts of kaolin powder, 10 parts of aluminum sulfate and 15 parts of sodium sul...

[0026]Take the rice husk and wash it, dry it naturally, and place it in a tube-type atmosphere furnace at 128 °C for 28 min, then pass nitrogen to remove the air, control the nitrogen flow rate to 130 mL / min, and raise the temperature to 480 °C at a rate of 5 °C / min under nitrogen protection. ℃, after heat preservation and carbonization for 2 hours, let it stand and cool to room temperature to obtain carbonized rice husks. In parts by weight, weigh 48 parts of carbonized rice husks, 13 parts of sodium fluoride and 18 parts of nano-iron powder, stir and mix them, and place them in graphite In the crucible, place the graphite crucible at 1350°C under an argon atmosphere for sintering treatment for 4 hours. After the sintering is completed, stop feeding argon and naturally cool to 720°C. After oxidation treatment for 6 hours, naturally cool to room temperature to obtain the modified material ; In parts by weight, weigh 50 parts of kaolin powder, 13 parts of aluminum sulfate and 18...
