Nuclear Magnetic Resonance and X-ray Photoelectron Spectroscopic Investigation of Lithium Migration in Montmorillonite
Lithium Migration Montmorillonite NMR Spectroscopy X-ray Photoelectron Spectroscopy
2011/12/22
Abstract: When Li-saturated montmorillonite is heated to 200?00 癈, the Li ions migrate from interlayer positions to sites in the layer structure. However, the identity of these sites has not been clea...
X-ray Photoelectron Spectroscopic Study of Cobalt(II) and Nickel(II) Sorbed on Hectorite and Montmorillonite
Cation exchange Cobalt Hectorite Ligand exchange Montmorillonite Nickel X-ray photoelectron spectroscopy

Abstract: The safe disposal of 60Co, 63Ni, and 59Ni has required considerable information on the interactions of Co2+ and Ni2+ with clay minerals in the geosphere. X-ray photoelectron spectroscopy (XP...
X-ray Photoelectron Spectroscopic Study of the Effect of Heating on Montmorillonite Containing Sodium and Potassium Cations
Montmorillonite Noncrystalline Surface composition Thermal treatment X-ray photo-electron spectroscopy X-ray powder diffraction
2012/1/13
The effect of heating on montmorillonites containing exchangeable Na and K has been studied by X-ray photoelectron spectroscopy (XPS). The surface composition of the unheated montmorillonite was consi...
Adsorbed Cr(III) on Chlorite, Illite, and Kaolinite: An X-ray Photoelectron Spectroscopic Study
Adsorption Binding energy Chlorite Chromium Illite Kaolinite XPS
2012/2/8
The adsorption of Cr(III) was studied at pH 1, 2, 3, 4, 6, 8, and 10 on chlorite and kaolinite and at pH 1, 2, 3, and 6 on illite. The amount of chromium adsorbed on chlorite varied from 3.1 × 10ͨ...
