▎ 摘  要

NOVELTY - Method for preparing adsorption material involves (a) preparing carrier by mixing 100-200 pts. wt. activated carbon powder, 20-50 pts. wt. expanded vermiculite particles and 5-10 pts. wt. graphene, hot pressing mixture thrice at 200-300 degrees C and 0.15-0.3 MPa for 30-60 minutes, at 300-600 degrees C and 0.5-1 MPa for 30-60 minutes, and at 600-800 degrees C and 1-5 MPa for 1-3 hours, and reducing pressure, and (b) preparing adsorption filler comprising 10-20 pts. wt. diatomite, 1-5 pts. wt. titanium oxide and 10-20 pts. wt. coagulant, and attaching the adsorption filler to carrier. USE - The method is useful for preparing adsorption material, which is used for treating polluted water (claimed). ADVANTAGE - The method is cost-effective.
