Abstract
The liquid–liquid extraction of Cu(II) from sulfate medium [Na_2SO_4] = 0.33 mol l^-1 of constant ionic strength (I=1.0 mol kg^-1) with capric acid (HL) in cyclohexane at 283K, 293K, 303K, 313K, and 323 K has been investigated. By using the slope analysis method the stoichiometry of the organometallic complex extracted was determine. At the end of this research, we have found that stoichiometry of Cu(II) complex is of the type CuL_2(HL)_2. The extraction of this metal increased with the increase of temperature. The values of the equilibrium constant have been calculated as well as the values of the thermodynamic parameters ΔH°, ΔS° and ΔG°.
