| titleOfInvention | Modified biochar for adsorbing high-concentration phenol-containing wastewater and preparation method thereof |
| abstract | The present invention provides a method for preparing modified biochar for adsorbing high-concentration phenol-containing wastewater, which comprises the following steps: washing biomass, naturally air-drying, pulverizing and sieving; Pyrolysis in the atmosphere to obtain biochar; mixing nitric acid and tannic acid to obtain a mixed solution, and then diluting the mixed solution with deionized water to obtain a diluted solution; adding biochar to the diluted solution, heating in a water bath, stirring, washing, and drying , that is, the modified biochar is obtained. The modified biochar of the invention has excellent adsorption performance and has a good adsorption effect on phenolic pollutants in wastewater; the invention uses a mixed solution of nitric acid and tannic acid to chemically modify the biochar, thereby increasing the specific surface area of the biochar and pore volume, providing more adsorption sites for the adsorption of phenolic organic pollutants, and significantly improving the treatment efficiency of phenol-containing wastewater; at the same time, the preparation method of modified biochar is low in cost, and the regeneration rate of modified biochar is high. High economic value and availability. |
