specific Embodiment approach 1
[0036] Specific embodiment one: the preparation method of needle-shaped Fe-Mn-S ternary nanomaterial loaded porous biochar composite material in this embodiment comprises the following steps:
[0037] 1. Pyrolytic carbonization of biomass materials;
[0038] cutting the biomass material, washing it with distilled water for 3 to 10 times, drying it, pulverizing it, passing through a 20-mesh sieve to 100-mesh sieve to obtain a finely divided powder of the biomass material;
[0039] Mix and grind the finely divided biomass material powder and metal salt to obtain a mixture, place the obtained mixture in a tube furnace for carbonization, pass a protective gas into the tube furnace, heat up to 700-900°C for pyrolysis, and pyrolysis The time is 1 to 3 hours, and the porous biochar material after pyrolysis and carbonization is obtained;
[0040] Wherein the mass ratio of the biomass material finely divided powder to the metal salt is (1~5):(1~5);
[0041] 2. Hydrophilicize the poro...
specific Embodiment approach 2
[0045] Embodiment 2: This embodiment differs from Embodiment 1 in that the biomass material described in step 1 is one or a mixture of eucalyptus leaves, corn stalks, sawdust, and bamboo stalks. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0046] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the metal salt described in step one is KHCO 3 , NaHCO 3 、K 2 CO 3 、Na 2 CO 3 one or a mixture of several. Others are the same as in the first or second embodiment.
