The solutions obtained from rare earth element (REE) processing are often acidic. The low pH is a challenge in the separation of REE. Hence, this study focuses on separating Ce(III) from acidic solutions by the ion exchange method using Dowex 50W-X8 resin. In the batch system, the maximum of Ce(III) exchange occurred at a resin dosage of 0.16 g, temperature of 35 °C, and sulfuric acid concentration of 0.2 M. The Ce(III) exchange process achieved equilibrium in 6 h with a capacity of 10.34 mg g<s
