The adsorption of uranium (VI) from phosphoric acid onto modified carbon has been investigated using a batch adsorber. The parameters that affect the uranium adsorption such as stirring time, carbon pH, solution pH, phosphoric acid concentration, temperature, modified carbon to phosphoric acid phase ratio and uranium oxidation state have been studied. Also, the factors affect on the modification of carbon such as the solvent concentration and soaking time were investigated. The thermodynamic parameters (?Hads. = -51.60 and -53.70 while ?Sads. = -166.07 and -170.03) showed the exothermic heat of adsorption and the feasibility of the process.
