Binding ability of acetamide oxime with proton, copper(II), and dioxouranium(VI) in aqueous solutions

Abstract

The equilibrium constant of acetamidoxime (acetamide oxime) with proton in aqueous solutions was determined using the potentiometric method. The compositions and stability constants of the complexes of this ligand with Cu^II and U^VIO₂ in aqueous solutions were also determined. Acetamidoxime forms 1 : 1 and 1 : 2 complexes with Cu^II and U^VIO₂. Furthermore, the U^VIO₂ complexes were found to be more stable than those of Cu^II; these characteristic properties of the ligand are discussed in relation to the recovery of uranium from sea water.
