Extraction of Pr3 + with the Acidic Phosphorus – containing Extractant

In this paper, the extraction properties of the praseodymium in light rare earth extracted with P204 and Ps07 were studiedand narrated. Experiments are carried out under the conditions of different extraction factors, ph value, extractant concentration,duration of oscillation and extractant volume fraction. With repeated trials, reasonable improvements are made to the extractionconditions, which have enabled the extraction properties of the praseodymium in light rare earth extracted with P204 and P507 toperform better.
