| Abstract | Metallic membranes with minipores have been used in the rotating disc diffusion cell (RDC) for the quantitative study of the effect of diffusion on the kinetics of solvent extraction. A study of the mass transfer of KCI through the membrane at different rotational speeds showed that the hydrodynamic conditions on the both sides of the membrane are reproducible. A kinetic study of iron(III) extraction from sulfate solutions with primary amine N-1923 and TBP (tri-butyl phosphate) was performed with the modified RDC after cell calibration. The results showed that the rate-limiting step in the extraction process is chemical reactions at the interfaces. The effects of various parameters on the rate of extraction suggested that the reaction order may be 1, 1, - 1 and 0 with respect to the concentrations of iron(III), amine sulfate, hydrogen ion and TBP, respectively. Due to the change in the reaction mechanism, the rate of extraction increased by one order of magnitude with the addition of TBP to the primary amine system.; Metallic membranes with minipores have been used in the rotating disc diffusion cell (RDC) for the quantitative study of the effect of diffusion on the kinetics of solvent extraction.
