| Abstract: |
| Rare earth elements were extracted by adding Mextral336A into Mextral204P. The effects of mole ratio of mixed extractant, extraction time, pH value of aqueous phase, and concentration of rare earth elements on extraction were investigated. The results show that with mole fraction of Mextral204P in mixed extractant of 0.75, the maximum positive synergistic effect is obtained between mixture extractant. The maximum samarium load is 23 g/L under the optimum conditions including extraction time of 4 min, phase ratio of 1︰1, and pH value of aqueous phase of 4. |
