Effect of diluents on Ag+ extraction was studied using the extractant D2EHPA.
Various diluents which have different dielectric constants were selected.
Equilibrium data of water + D2EHPA + diluents exhibited type-2 LLE behavior.
Efficiency and stoichiometry of Ag+ extraction changed in the different diluents.
rmsd values for modeling and experimental correlations were less than 1%.
