Abstract

The conditions of complexation of 1,2-diacylhydrazines (H2L) C6H5C(O)NHNHC(O)R, where R = C6H5 or CH3, with Cu(II) ions in alkaline solutions were studied. The composition of the complexes formed by precipitation of Cu(II) from alkaline solutions, (CuOH)2L and CuL, was determined. The possibility of afterpurification of solutions with a low Cu(II) content by pneumatic flotation using H2L was examined.
