Embodiment 1
[0013] The preparation method of the biomass powder activated carbon of the present embodiment may further comprise the steps:
[0014] A, after the walnut shell is dried through 70 ℃ of heating earlier, be pulverized to particle diameter with pulverizer again and be 900 mesh particles;
[0015] B. Stir and mix the walnut shell particles prepared in step A with calcium hydroxide and potassium hydroxide in a mass ratio of 1:1:0.20, and add water just enough to completely soak the mixture in water for 3 hours to expand after drying;
[0016] C, the dried mixture obtained in step B is placed in a hierarchical tubular heating furnace, heated by microwave radiation, and then naturally cooled;
[0017] D. Mix and soak the cooling material obtained in step C with 1.5mol / L hydrochloric acid according to the solid-to-liquid ratio of 1:10, stir and soak, process for 12 hours under constant stirring, filter, and then rinse with distilled water until Neutral, drying; the dried product w...
