NOVELTY - Method for preparing photothermal-enhanced antibacterial biomass/graphene aerogel uranium adsorbent, involves (a) cleaning bacteriostatic biomass, drying, crushing and sieving to obtain a bacteriostatic biomass powder, and (b) mixing oxidized graphite powder with ultrasonic deionized water for obtaining a graphene oxide aqueous solution, adding amidoximated diaminomaleonitrile and bacteriostatic biomass powder into the graphene oxide aqueous solution, uniformly stirring, hydrothermally reacting at 70-200℃ for 6-24 hours, and immersing the obtained product in water/ethanol solution and freeze-drying to obtain the product. USE - The photothermal-enhanced antibacterial biomass/graphene aerogel uranium adsorbent used for enrichment of hexavalent uranium in a water body (all claimed) . ADVANTAGE - The adsorbent exhibits high mechanical strength, high photo-thermal conversion capacity, high antibacterial and environmentally friendly performance, and has unique and excellent adsorption performance, excellent material stability, high repetitive usage rate and strong absorptive power performance after 10 cycles of regeneration.
