[0036] Embodiment 1, the preparation of activated carbon material derived from edamame hulls

[0037] The preparation method of the activated carbon material derived from edamame hulls, the specific steps are as follows:

[0038](1) Put the edamame shell powder with a particle size of 60 mesh in a tube furnace, under the protection of argon, raise the temperature at a rate of 5 °C / min to 200 °C for 1 hour, and then continue to heat up at a rate of 5 °C / min to Insulate at 400°C for 1 hour, then raise the temperature at a rate of 5°C / min to 800°C for 3 hours, and finally cool to room temperature to obtain a crude carbon material precursor derived from edamame hulls;
