Chemistry, Physics and Technology of Surface| Summary: | Anchorage of 4-(2-pyridylazo)-resorcinol and 1-(2-pyridylazo)-2-naphthol on the surface of silica-polyaniline composite has been carried out using the Mannich reaction. Complexing and ion?exchanging properties of the synthesized adsorbents with respect to cationic and anionic forms of transition metals were studied. Modified with heterocyclic azo reagents composites were shown to adsorb cations of toxic metals via their complexation with the grafted groups and to serve inherent to the pristine silica-polyaniline composite ion?exchanging properties towards anionic forms of multivalent metals. |
