NOVELTY - Preparation of groundwater remediation materials involves modifying carbon fiber to obtain modified carbon fiber, feeding modified carbon fiber in container, adding 0.5-1.5 g, preferably 0.7-1.2 g graphene oxide, 0.1-0.2 g, preferably 0.12-0.18 g ascorbic acid and 10-15 mL distilled water, mixing well to obtain mixed solution, placing mixed solution at temperature of 90-100 degrees C for 6-8 hours, subjecting mixed solution after reaction to vacuum freeze-drying at -15 degrees C to -8 degrees C. USE - Preparation of groundwater remediation materials. ADVANTAGE - The prepared product is close contact with the surface of carbon fiber and graphene oxide, chemical changes have occurred on the surface of carbon fiber and graphene oxide, and increases specific surface area of the repair material, and has strong adsorption, thereby entering the groundwater that has high removal efficiency of heavy metals, and there is no secondary pollution to groundwater.
