Abstract:Mixed extractant of P292 and Alamine336 was applied to extract rare earth. The results show that the two extractants have positive synergistic effect on extraction of rare-earth elements. When they were mixed with volume ratio of 2︰3, higher extraction rate is obtained with extraction time of 3 min and O/A=4/1. The load organic phase after extraction of rare earth can be completely stripped by 1.5 mol/L hydrochloric acid. Organic phase can be fully regenerated after mixing organic phase with equal volume neutral water for triple times. This experiment shows good reproducibility and repeatability.
