Surface| Резюме: | In situ immobilization of polyaniline on the surface of bentonite, vermiculite, saponite and clinoptilolite was carried out by oxidative polymerization of aniline with ammonium peroxodisulfate in the acidic medium. The fact of even polymer distribution on the surface of all minerals was studied by thermogravimetric analysis, processing of nitrogen adsorption-desorption isotherms, pore distribution curves and scanning electron microscopy. It was established that all studied minerals after modification with polyaniline have shown high adsorption capacity with respect to Cr(VI), Mo(VI) and W(VI) oxoanions and the highest adsorption capacity have been recorded for the modified saponite. A high adsorption capacity of clinoptilolite and saponite modified with polyaniline was found towards P(V) and As(V) oxoanions. |
