Abstract	:	The use of active carbon (AC) as a potential adsorbent for the removal of uranium from aqueous solution has been investigated. Two principal areas have been studied i.e. uranium adsorption from near-neutral and dilute acidic solutions and uranium adsorption from concentrated acid solutions. The aqueous solution matrix used was nitric acid. In the former case commercial (as-received) and oxidized active carbons were investigated. It was noticed that oxidation of as-received ACs with nitric acid solution significantly improves the adsorption capacity of uranium from both near-neutral and dilute acidic solutions. Oxidized ACs were particularly effective in dilute acidic solution , whilst as-received ACs have shown little uranium sorption. Batch equilibrium isotherms were constructed to compare the adsorption capacities of as-received and oxidized ACs. The batch kinetics of uranium adsorption was studied and a column experiment was performed.
