[0034] In the present embodiment, the preparation method of the pomelo peel magnetic activated carbon comprises the following steps:
[0035] a. Wash and dry pomelo peels, soak them in hydrochloric acid pickling water for 24 hours, and then dry them at 120-125°C for 12 hours to obtain impregnated samples;
[0036] b. Place the impregnated sample prepared in step a in a carbonization furnace, carbonize at 670°C in a nitrogen atmosphere for at least 1 hour, then cool to room temperature in a nitrogen atmosphere, then take out the carbonized solid and wash it with distilled water until the filtrate It is neutral, and then the washed solid is dried and pulverized; the preparation method is simple, and the cheap agricultural residue pomelo peel is used for preparation, turning waste into treasure, and the cost is low.
[0037] In the present embodiment, described hydrochloric acid pickling water comprises following composition according to concentration:
[0038] HCl 170-180g / L,
