The recovery of cobalt, copper, zinc, and manganese ions from technical solutions by the modified natural zeolites of the Aidag deposit (Azerbaijan) is experimentally studied. The results obtained show that the zeolite modified with monoethanolamine can be used as an efficient sorbent for the recovery of Co2+, Cu2+, Zn2+, and Mn2+ ions from technical solutions. The adsorption ability of the metal ions depends strongly on the pH of the solution and the initial concentration of the metal ions. The order of selectivity of the metal ions on the zeolite modified with amines is as follows: Co2+ > Cu2+ > Zn2+ > Mn2+. The data on the adsorption of the studied systems are interpreted on the basis of the Langmuir and Freundlich isotherms. The results obtained show that the Langmuir regions are consistent with the experimental data.
