Characterization of Silanol Groups in Protonated Magadiite by 1H and 2H Solid-State Nuclear Magnetic Resonance
1H NMR 2H NMR Hydrogen Bonding Magadiite Silanol Group
2011/12/6
Abstract: Silanol groups in protonated magadiite (H-magadiite) were characterized by 1H and 2H solid-state nuclear magnetic resonance (NMR). H-magadiite and deuterated (D) magadiite were synthesized b...
Effects of Iron Oxidation State and Organic Cations on Dioctahedral Smectite Hydration
Alkylammonium Ferric Iron Ferrous Iron HDTMA Hydrophilic Surface Hydrophobic Surface Interlayer Cation Oxidation Reduction Surface Hydration Swelling TMA TMPA
2011/12/6
Abstract: Reduction of structural Fe in Na-exchanged dioctahedral smectites decreases swellability in water, but because clay interlayers also collapse in the process the concomitant effect on surface...
