[0016] First pick fresh 2kg poplar branches, 3kg peach branches, and 2kg locust tree branches, peel them, expose them to the sun for 3 days, make their water content reach 15%, and place them in a charcoal rod making machine Make it into a carbon rod, control the pressure at 0.6MP, and the temperature at 40°C; put the charcoal prepared above in a charcoal kiln, heat it up to 200°C, react for 45min, and keep it warm for 2h, then continue to heat up to After reacting for 2 hours at 400°C, let it cool down to room temperature naturally, and then take out the carbonized charcoal; then soak the above carbonized charcoal in absolute ethanol solution for 40 minutes, take it out, and put it in a pulverizer for crushing into After 120 mesh particles, mix with bauxite and fly ash in a mass ratio of 3:1:1, and dry it at low temperature to make its water content to 2%, to obtain a dry mixture; then the dry mixture prepared above Soak it in a hydrochloric acid solution with a mass fraction...
