Sorption–desorption of cadmium in aqueous palygorskite, sepiolite,and calcite suspensions: Isotherm hysteresis
Cd Hysteretic adsorption Release Reversibility
2011/11/4
Sorption isotherms have been widely used to assess the heavy metal retention characteristics of soil particles. Desorption behavior of the retained metals, however, usually differ from that of sorptio...
Montmorillonite under high H2O pressures: Stability of hydrate phases, rehydration hysteresis, and the effect of interlayer cations
Montmorillonite high H2O pressures Stability hydrate phases rehydration hysteresis effect interlayer cations
2012/4/1
Dehydration of Ca- and Mg-exchanged montmorillonite was studied along H20 iso-
chores in the hydrothermal diamond-anvil cell by in situ X-ray diffraction using a syn-
chrotron radiation source. At-r...
Hysteresis in the Binary Exchange of Cations on 2:1 Clay Minerals: A Critical Review
cation exchange hysteresis quasi-crystal crystalline swelling kinetics smectites
2011/12/28
The binary exchange of cations on clays and soils is generally regarded as a thermodynamically reversible process. The literature on soil chemistry and geochemistry, however, abounds with reports on c...
Changes in the Properties of a Montmorillonite-Water System during the Adsorption and Desorption of Water: Hysteresis
Adsorption Desorption Hysteresis Infrared spectroscopy Montmorillonite Vapor pressure Water
2012/1/4
Samples of Na-saturated, Upton montmorillonite were prepared with different contents of water (H2O or D2O) by: (1) adsorption of water from the vapor phase at a specific value of p/p°, the relative hu...
