A method is proposed for the removal of EDTA (ethylenediaminetetraacetate) in the form of the insoluble compound Cu₂EDTA·4H₂O from complex solutions of heavy metals, such as Ni(II), Zn(II), Co(II), Cd(II), Ca(II), and Mg(II). The formation of the insoluble Cu₂EDTA·4H₂O precipitate occurs in the pH r...
