EN The model oximes of 1-(2-pyridyl)undecane-1-one (2PC10), 1-(2-pyridyl)tridecane-1-one (2PC12) and 1-(4-pyridyl)tridecane-1-one (4PC12) were synthesized and used for copper(II) extraction from chloride solutions. The behavior of these ligands towards copper(II) extraction was investigated for different experimental conditions with a particular emphasis on the influence of the concentrations of copper ions, chloride ions, and ligand. The obtained results indicated the ability of pyridylketoximes to extract copper(II) from chloride solutions. 2-Pyridyl ketone oximes are stronger extractants of copper than 4-pyridyl ketone oximes. Copper can be effectively stripped by water or diluted sulfuric acid.
