Complexation of copper (II) ions with naphthenic acids in organic solutions
Authors:
Abstract
Naphthenic acids are good extractants for heavy non-ferrous metal ions, with each metal ion being extracted in a specific region of pH values. It has been shown that Cu2+ copper ions begin to be extracted at a pH of 3.2-3.7, depending on the concentration of copper in the aqueous phase, the concentration of naphthenic acid in the organic phase, and the ratio.
