A kind of modified rice husk biomass carbon and preparation method thereof |
| abstract |
The present invention relates to a rice husk biomass charcoal and a preparation method thereof, comprising the following steps: S1. Drying: sieving the collected rice husks to remove impurities, and putting them into an oven for drying; S2. High temperature pyrolysis: drying After the rice husks in step S1 are cooled, put them into a tube furnace, and heat up and pyrolyze in a nitrogen atmosphere to obtain biomass carbon; S3. Modification of potassium permanganate: grinding and sieving the biomass carbon obtained in step S2 Small particles of biomass charcoal, potassium permanganate and deionized water are placed in a vibrator and shaken to fully oxidize the surface of the biomass charcoal, and then deionized water is used to wash away the impurities remaining on the biomass charcoal after oxidation. , and the modified rice husk biomass charcoal was obtained after drying. The purpose of the present invention is to use rice husk as raw material, pyrolysis by temperature-programmed method under nitrogen atmosphere, and use potassium permanganate as modification agent to modify and prepare rice husk biomass carbon, and apply it to PAHs naphthalene pollution treatment It can further improve the adsorption effect of biomass charcoal, and can be applied to the pollution control of water body and soil at the same time. |
