Abstract

The extraction of Co2+ by a mixture of acetylacetone (acac) and pyridine (py) from an aqueous phase of varying ionic strengths has been investigated. The extraction studies were done at different temperatures in order to determine the effect of changes in the ionic strength on the free energy ΔG, enthalpy ΔH and entropy ΔS of the synergistic reaction.
