The extraction efficiency for all of the metals was negligible at low TODGA concentrations. While increasing TODGA concentration up to 0.1 mol.L −1, the extraction efficiency for manganese(II) can reach values up to 90% while cobalt(II) is only slightly extracted (less than10%) and no nickel(II) nor lithium(I) is extracted (Fig. 3). With a ...
