The solvent extraction of rare earth elements (REEs) from their mixed solution in nitrate acid was performed. The experimental results showed that the extraction rates of La, Ce, Pr, Nd, and Y were 54.5%, 45.33%, 51.33%, 55.33%, and 89.77%, respectively, by the extractant, D2EHPA. Different operating parameters have been studied to get the optimum conditions, and the results showed that D2EHPA has a strong extraction ability for REEs, especially for yttrium.
