Embodiment 1
[0025] Take 2g of fir bark powder, put it in a glass beaker, add 6g of potassium hydroxide solid, then add 50ml of deionized water, then stir with a magnetic stirrer at a speed of 800r / min for 30min, and transfer the stirred mixed solution to a poly In a tetrafluoroethylene high-pressure reactor, place it in a microwave hydrothermal synthesizer under the condition of 180°C and 1.8MPa for the reaction, follow the temperature program for 10 minutes, then cool it down to room temperature naturally, take it out, and dry it in a vacuum oven at 105°C for 10 hours. Then put the dried powder in a sintering furnace at 500°C, sinter for 2 hours under nitrogen, pickle with 1M hydrochloric acid solution twice, then wash with deionized water until neutral, and get a Chinese fir bark after drying Microwave hydrothermal activated carbon.
Embodiment 2
[0027] Take 2g of fir bark powder, put it in a glass beaker, add 6g of potassium hydroxide solid, then add 50ml of deionized water, then stir with a magnetic stirrer at a speed of 800r / min for 30min, and transfer the stirred mixed solution to a poly In a tetrafluoroethylene high-pressure reaction kettle, place it in a microwave hydrothermal synthesizer under the condition of 180°C and 2MPa for the reaction, follow the programmed temperature rise for 15 minutes, then cool it down to room temperature naturally, take it out, and dry it in a vacuum oven at 105°C for 11 hours, then The dried powder is placed in a sintering furnace at 600°C, sintered under nitrogen for 2 hours, pickled twice with 1M hydrochloric acid solution, washed with deionized water until neutral, and dried to obtain a fir bark microwave Hydrothermal activated carbon.
Embodiment 3
[0029] Take 2g of fir bark powder, put it in a glass beaker, add 6g of potassium hydroxide solid, then add 50ml of deionized water, then stir with a magnetic stirrer at a speed of 800r / min for 30min, and transfer the stirred mixed solution to a poly In a tetrafluoroethylene high-pressure reaction kettle, place it in a microwave hydrothermal synthesizer under the condition of 180°C and 2MPa to carry out the reaction, follow the programmed temperature rise reaction for 20 minutes, then cool down to room temperature naturally, take it out and place it in a vacuum oven at 105°C to dry for 12 hours, and then Put the dried powder in a sintering furnace at 700°C, sinter for 2 hours under nitrogen, pickle with 1M hydrochloric acid solution twice, and then wash with deionized water until neutral. After drying, a fir bark microwave Hydrothermal activated carbon.
