Αcid-base properties of 3 aminopropyl-containing xerogels
Acid-base properties of amine group-containing xerogels synthesized by sol-gel technique have been studied by pH-metric titration. Protonation (lgKprot) and conjugation (lgKcon) constants of surface 3-aminopropyl groups were calculated using electrostatic model and that of chemical reaction. An inc...

Surface| Zusammenfassung: | Acid-base properties of amine group-containing xerogels synthesized by sol-gel technique have been studied by pH-metric titration. Protonation (lgKprot) and conjugation (lgKcon) constants of surface 3-aminopropyl groups were calculated using electrostatic model and that of chemical reaction. An increase has been found in lgKprot with surface amino group concentration in xerogels whereas no dependence of lgKcon on their concentration has been revealed. |
