Abstract

Theoretical evaluation of experimental extraction data of U (VI) from nitric acid solutions by tri-n-butyl phosphate (TBP) loaded on macro reticular polymer SM-7 was verified using Thomas and Yan models. These data are represented by breakthrough relations at different conditions; flow rate, concentrations and interfering ions. Comparing correlation coefficients (R 2) of both models, it was found that R 2 equal 0.96 for Thomas model comparing to 0.88 for Yan one, indicating that Thomas model is convenient for evaluation of that extraction process. The calculated, theoretically, value of (q Th) was found to be almost equal to (qexp ) the practical one.
