Wastewaters often contain offensive cations. Because of their high affinity for water, it is difficult to remove those using conventional solvents for liquid- liquid extraction . Hydrophobic ionic liquids may provide a useful extraction process. Because the properties of ionic liquids are turnable, it may be possible to identify some ionic liquids that have low viscosity, very low solubility in water, and high affinity for select metal ions . In this sense in this work liquid- liquid extraction of dilute Zn ions from water was performed near room temperature with two ionic liquids (IL). Distribution coefficients are reported for Zn ions extracted with bromide 1-hexyl-pyridinium and bromide 1-octyl-pyridinium diluted in decanol. The extraction has been studied, and these confirmed that the metal extraction proceeds via a cation – exchange mechanism. Furthermore, stripping of Zn (II) from ILs into an aqueous phase by sulfuric acid (1 M) and recycling of the extracting ILs phase was successfully accomplished.
