Equilibrium Concentrations Distribution of Copper(II) with Di-Schiff Base in Hollow Fibers Contactor Membrane

The equilibrium concentrations in membrane contactors are investigated in closed system for the extraction of copper from sulfate medium with di-Schiff base in toluene. The equilibrium distribution curves, is carried out from the mass action law, allows the determination of the reaction equilibrium constant. The calculation of the distribution coefficient in the membrane contactor is carried out from global mass balances and extraction isotherms. The experimental distribution coefficient is compared with the calculated value. The influence of parameters as the aqueous and organic phase flowrates and the distribution coefficient on the sensitivity of the system has been checked with experimental data.
