Mossbauer Spectroscopic Evidence for Citrate-Bicarbonate-Dithionite Extraction of Maghemite from Soils
Mossbauer spectroscopy Soil genesis
2011/12/1
Abstract: In a previous paper, we used powder X-ray diffraction and changes in magnetic susceptibility to argue the importance of pedogenic maghemite to soils and the efficacy of the chemical extracta...
I.R. Spectroscopic Evidence for Interaction between Hydronium Ions and Lattice OH Groups in Montmorillonite
I.R. Spectroscopic Hydronium Ions Lattice OH Groups Montmorillonite
2011/11/17
Abstract: At low levels of hydration, exchangeable D+ in montmorillonite interacts with lattice OH groups and quantitatively converts AlMgOH groups to AlMgOD. Hydroxyl groups coordinated to two Al ion...
