| description | The invention provides a preparation method of an adsorbent for adsorbing dye-containing wastewater. The preparation method is characterized in that hexabromobenzene and calcium carbide are used as raw materials, and the adsorbent is prepared by a mechanochemical method, the mechanochemical method comprises the following steps: step 1, grinding the calcium carbide into powder, adding absolute ethyl alcohol into the powder and hexabromobenzene, and carrying out ball milling; step 2, drying the sample after ball milling, calcining, and removing unreacted hexabromobenzene to obtain a crude product; and step 3, washing and drying the crude product obtained in the step 2 to obtain the adsorbent for adsorbing dye-containing wastewater. The adsorbent for adsorbing dye-containing wastewater is high in adsorption rate, and the removal rate of a 30 mg/L rhodamine B solution within 10 minutes reaches 95% or above. The adsorption capacity to rhodamine B reaches up to 386.10 mg/g, the adsorption capacity to methylene blue |
