Embodiment 1
[0032] (1) Preparation of nut shell-based activated biochar: Weigh 500g of nut shells, dry them, place them in a high-energy planetary ball mill for 6-8 hours, and feed N into the vacuum tube furnace. 2 , and put the ball-milled nut shell powder into a vacuum tube furnace at a heating rate of 10°C / min, the temperature rises to 750-760°C, and heats for 4 hours. After the reaction, stop heating, and cool the material to room temperature, and Put the material in a high-energy planetary ball mill until all the materials pass through a 100-110 mesh screen to obtain a biochar prediction, and then add 300mL 0.1-0.15mol / L of dilute HCl solution, then add biochar, stir at a constant speed for 1-1.5min, filter the material, wash it with 1500-2000 mL of distilled water, then add 400mL of 0.08-0.12mol / L NaOH solution to another 1000mL beaker , then add acidified biochar, stir at a constant speed for 1-1.5h, filter the material, wash with 2000-2500mL distilled water, then heat the materia...
Embodiment 2
[0037] (1) Preparation of nut shell-based activated biochar: Weigh 500g of nut shells, dry them, place them in a high-energy planetary ball mill for 6-8 hours, and feed N into the vacuum tube furnace. 2, put the ball-milled nut shell powder into a vacuum tube furnace, the heating rate is 10 °C / min, the temperature is raised to 750-760 °C, and heated for 4 hours. After the reaction is completed, the heating is stopped, and the material is cooled to room temperature, and The material is then placed in a high-energy planetary ball mill for ball milling until all materials pass through 100-110 mesh sieves, and the biochar is expected to be obtained. L of dilute HCl solution, then add biochar as expected, stir at a constant speed for 1-1.5min, filter the material, wash it with 1500-2000 mL distilled water, and then add 400 mL of 0.08-0.12mol / L NaOH solution to another 1000 mL beaker , then add the acidified biochar as expected, stir at a constant speed for 1-1.5h, filter the materi...
