This study investigates the extraction of uranium from phosphoric acid solutions through the use of various chelating ion-exchange resins, including RSPO, Diaion-CRP200, Diphonix, Purolite S940, Duolite ES467, and Lewatit OC 1060, as well as a specific solvent containing ion-exchange resins known as Actinide-CU. Experimental measurements were conducted in batch conditions to assess the kinetic performance of these resins. The impact of ions Fe(II) and Ca(II) on the processes of sorption and elution was also thoroughly examined. The results indicated that the Actinide-CU resin displayed significant efficacy in uranium removal from phosphoric acid solutions; however, its elution performance was suboptimal with both acidic and carbonate eluants. Conversely, the chelating resins Diphonix, Duolite ES467, Lewatit OC 1060, and Purolite S940 demonstrated reasonable uranium sorption even in the presence of Fe(II) ions during batch trials. Notably, effective desorption of uranium was achieved quantitatively using carbonate eluants, and small-scale column extractions utilizing Purolite S940 yielded promising loading and elution profiles.
