Solid-liquid extraction of uranium from industrial phosphoric acid using macroporous cation exchange resins: MTC1600H, MTS9500, and MTS9570

The main objective of this research work is the application of a series of Purolite commercial resins: sulfonic cationic exchanger (MTC1600H), amino phosphonic-chelating resin (MTS9500), and phosphonic/sulfonic chelating reins (MTS9570) for uranium adsorption from crude dihydrate phosphoric acid. The impact of various parameters on the sorption efficiency such as shaking time, sorbent dose, phosphoric acid concentration, and reaction temperature has been investigated. The obtained data showed that the chelating resins MTS9500 and MTS9570 exhibit higher sorption efficiency than the cationic exchange resin MTC1600H. Kinetic, isotherms, and thermodynamics analysis for the obtained data has been performed.
