Chemistry, Physics and Technology of Surface| Резюме: | Zinc (II) sorption on a surface of nanoporous silicas chemically modified with functional derivatives of ?-cyclodextrin from slightly acidic dilute solutions of zinc nitrate has been studied. Structure and chemical composition of nanoporous organosilica surfaces have been revealed by elemental and chemical analysis, UV and IR spectroscopy, and also sorption measurements. Active sites for zinc cation sorption has been identified. The relationship has been found between the sorption affinity of ?-cyclodextrin-containing organosilica surfaces and the chemical nature of side functional substituents of wide ring of grafted ?-cyclodextrin molecules. |
