NOVELTY - Preparation of phosphate adsorbent based on three-dimensional (3D) reduced graphene oxide (rGO)/zirconium dioxide composite material comprises preparing GO by a conventional method, and preparing into 3 mg/ml solution using deionized water according to need; dissolving 30-60 mg zirconium oxychloride octahydrate (ZrOCl2.8H2O) and 50 mg glutamic acid in 1 ml deionized water, and ultrasonically processing for 10 minutes; mixing the obtained mixed solution with 3 ml of 3 mg/L GO dispersion liquid, and performing hydrothermal reaction at 180 degrees C for 6 hours; and collecting the product after reaction, washing and drying. USE - The method is for preparation of phosphate adsorbent based on 3D rGO/zirconium dioxide composite material used for adsorbing phosphate ions (claimed). ADVANTAGE - The method provides product, which has regular shape, three-dimensional structure, and high efficiency for adsorbing phosphate radical. It is simple and suitable for large-area application and has low cost.
