NOVELTY - Manufacturing uranium adsorbent, comprises (c) doping graphene oxide with metal-organic framework (MOF). USE - The uranium adsorbent is useful for removing uranium contained in water i.e. groundwater. ADVANTAGE - The method removes uranium contained in water with high efficiency, uranium adsorbent can be easily separated from the water, so it can be easily applied to actual groundwater. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: removing uranium contained in water, comprising introducing an adsorbent in which adsorbent is graphene oxide doped with a metal-organic framework (MOF); removing uranium in which sodium chloride (NaCl), sodium carbonate (Na2CO3) or sodium nitrate (NaNO3) is contained in the water; and regenerating adsorbent in which uranium is adsorbed, comprising injecting the uranium-adsorbed adsorbent into a mixture of sodium carbonate and hydrogen peroxide.
