Adsorption of Toxic Metal Ions onto Silica with Covalently Bound 8-Hydroxyquinoline
8-Hydroxyquinoline covalently bound to silica via a one-stage Mannich reaction was used as an adsorbent for the pre-concentration of Pb(II), Cd(II), Zn(II) and Mo(VI) ions from aqueous solutions in the dynamic mode following determination of their concentrations by X-ray fluorescence methods. The ad...

| Summary: | 8-Hydroxyquinoline covalently bound to silica via a one-stage Mannich reaction was used as an adsorbent for the pre-concentration of Pb(II), Cd(II), Zn(II) and Mo(VI) ions from aqueous solutions in the dynamic mode following determination of their concentrations by X-ray fluorescence methods. The adsorption of Pb(II), Cd(II), Zn(II) and Mo(VI) ions was studied from individual and complex multi-component solutions of both natural and technogenic origins. Peculiarities associated with the simultaneous X-ray fluorescence determination of mixtures of toxic metal ions in a solid matrix are discussed. |
