Water mobility in smectite     Water  mobility  smectite       2012/3/30
The hydrogen in smectite can be broadly separated into five major types according to the association with (i) structural hydroxyl groups, (ii) interlayer water bonded directly to the interlayer cation...
Abstract: Progressive alteration by seawater of an andesite in the Aegean Island of Milos and an ignimbrite in the Aegean Island of Kimolos, Greece, formed bentonites with or without zeolites. Both pr...
Mineralogical geochemical and mechanisms of fixation under oxidizing conditions inU the vicinity of the secondary U ore deposit at Koongarra, Australia,were examined usingtransmission and scanning e...
The form under which Ti occurs in kaolinitic materials from various environments has been investigated using second derivative diffuse reflectance spectroscopy. The position of the absorption edge may...
Electron spin resonance (ESR) spectroscopy was used to measure the rotational mobility of an uncharged nitroxide spin probe (4-hydroxy-2,2,6,6-tetramethyl-piperidinyloxy) in hectorite gels of variable...
The purpose of this study was to investigate bonding mechanisms of representative inorganic anions and citrate with imogolite and allophane using electrophoresis. The electrophoretic mobility (EM) of ...
The electron spin resonance (ESR) technique has been used to study the motion and segregation of an organic spin probe cation (4-amino-2,2,6,6-tetramethylpiperidine N-oxide) on K+-hectorite as a funct...
The electron spin resonance (ESR) spectra of varying quantities of vanadyl ion (VO2+) adsorbed on hydrated hectorite indicated that hydrolysis of VO2+ was promoted at low levels of adsorption. The hyd...
Abstract: The adsorption of nitroxide spin probes on smectites solvated in liquids of greatly different polarity was studied using electron spin resonance (ESR) spectroscopy. Adsorbed probes demonstra...
A new apparatus for the measurement of eleetrophoretie mobilities of particles in concentrated suspensions has been developed. The usual techniques for the study of electrophoretic mobility, such as t...
