Isotherms of Ge(IV) and Cu(II) ions sorption on to the weakly basic anion-exchange resin AN-31 from chloride solutions have been constructed and described. The dependence of equilibrium parameters of Ge(IV) and Cu(II) ions sorption from chloride ions concentration was shown. Based on the electron spectra of diffuse reflectance of copper-containing sorbent, isotherms of sorption and isomolar copper–germanium ions distribution diagram in solutions with different chloride concentrations the nature of extracted particles has been established, and the effect of the mineral background on the sorbent capacity has been determined. The synergistic effect of Cu(II) ions sorption in the presence of Ge(IV) ions has been established. It was found that the ionic and uncharged associates formed by hydroxy-chloride polynuclear cuprate(II) cations and methagermanate anions extract from the chloride solutions onto AN-31. The possibility of selective Cu(II) ions sorption from germanium containing 1 M chloride solutions in wide range of Ge(IV):Cu(II) molar ratios from 1:3 to 1:1 has been established. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.
