According to experimental results, some thermodynamic parameters such as distribution coefficients (K-D), loading factors (Z), and extraction efficiency (E) were calculated. The best extraction efficiency, distribution coefficient, and loading factor were determined by isoamyl alcohol diluent at values of 98 %, 97, and 4.6, respectively. Besides, the linear solvation energy relationship (LSER) model regressed to experimental results with a regression coefficient (R square) of 0.98. The LSER model predicts results close to experimental data.eninfo:eu-repo/semantics/closedAccessArticle10.1021/je300983b2-s2.0-84871025575368912Q2368557WOS:000312175600053Q2
