Three homologues of 4-pyridylketoximes were synthesized and used as potential ligands for zinc(II). Their solvent extraction behaviors for zinc(II) in chloride solutions were investigated using CHCl3 as the diluent. The effect of different variables on the extraction of zinc(II) ions, such as the pH of aqueous phase, metal and chloride ions as well as the type of oxime, has been investigated. Results indicated that 4-pyridylketoximes could extract zinc(II) ions from chloride solutions and the extraction depended on the concentrations of the ligand, chloride ions and hydrochloride acid. Slope analysis confirmed that the 4-pyridylketoximes ligands form a 1:2 complex with zinc(II) in both chloride/nitrate and chloride/perchlorate solutions. After extraction, zinc(II) could be easily stripped from organic phase with water.
