NOVELTY - Preparation of phosphene/graphene three-dimensional aerogel material comprises mixing red phosphorus, tin powder and tin iodide in ampoule bottle, vacuuming to not greater than 0.05 Pa, sealing tube, heating raw material end of ampoule bottle to 200 degrees C, heating to 600 degrees C for 6 hours and 300 degrees C for 2 days, cooling to room temperature to obtain black phosphorus, weighing black phosphorus, placing in test tube, adding N-methyl-2-pyrrolidone to test tube, centrifuging at 30 degrees C for 24 hours to obtain black solid, freeze-drying to obtain phosphorene, dispersing graphene oxide in deionized water to obtain graphene aqueous solution, dispersing phosphonene in deionized water to obtain phosphorus aqueous solution, mixing mixture for 3 hours at 30 degrees C and freeze-drying. USE - The preparation of phosphene/graphene three-dimensional aerogel material is used for uranium containing wastewater treatment (claimed). ADVANTAGE - The method reduces degradation of phosphorus in environment, improves stability of uranyl ion in the adsorption and separation of radioactive waste water, enhances overall uranium adsorption capacity of material and has strong selectivity for uranium adsorption and simple and controllable preparation process.
