The solubility and the coefficient of copper(II) distribution between hexane and aqueous phase of N,N-dibutylhydrazide of octanoic acid were studied. The effects of ammonium, Co(II), Ni(II), and Zn(II) salts on the copper(II) extraction was studied. The extraction isotherm was constructed and the constant of copper extraction from ammonium solutions was calculated. The capacity of the organic phase with respect to copper and the conditions of its reextraction were determined.
