Abstract

Abstract The conditions of complexation of 1, 2-diacylhydrazines (H 2 L) C 6 H 5 C (O) NHNHC (O) R, where R= C 6 H 5 or CH 3, with Cu (II) ions in alkaline solutions were studied. The composition of the complexes formed by precipitation of Cu (II) from alkaline solutions,(CuOH) 2 L and CuL, was determined. The possibility of afterpurification of solutions with a low Cu (II) content by pneumatic flotation using H 2 L was examined.
