Abstract


The extraction of Cu(II) from acidic sulphate aqueous solutions using the commercial MOC-55TD extractant is studied. A predictive model, which consists in a set of non-linear mass action and mass balance equations is proposed. The model was solved using a tailor-made equation-solving program. The extraction of copper can be described by the formation of CuR2 species (log Kext= 0.717 ± 0.03) in the organic phase. The copper equilibrium isotherm was also obtained at 20°C.
