| description | The invention discloses a preparation method and application of a biomass dye adsorbent. The preparation method comprises the steps of preparing monodisperse carbon microspheres by taking biomass saccharides as a carbon source and adopting a hydrothermal method under an acidic condition, adding the carbon microspheres into an organic solvent, reacting with epoxy chloropropane and an amino functional compound in a certain proportion, washing prepared powder with an alcohol-water solution, and drying to obtain the amino-modified carbon material. The amino-modified carbon material has larger specific surface area and more active sites, has excellent adsorption performance on anionic dyes, and can be applied to removal of dyes in wastewater. The preparation process is simple and convenient, the raw materials are green and environment-friendly, the thickness of the amino functional layer coated on the surface of the carbon microsphere is controllable, and the biomass dye adsorbent has a relatively strong adsorptio |
