| Abstract |
Solvent extraction experiments have been performed to separate Gd and Sm from chloride solution with PC88A and saponified PC88A. The effects of extraction conditions on the distribution coefficients of Gd and Sm were investigated. The distribution coefficients of Gd were higher than those of Sm in the experimental ranges of experimental conditions of this study. A solvent extraction model was developed to predict the distribution coefficients of metals and separation factor between Gd and Sm from the initial extraction conditions. The measured distribution coefficients of Gd and Sm with PC88A and saponified PC88A showed good agreements with the predicted values. (Received March 3, 2005) |
