Infrared Study of Water Sorption on Na-, Li-, Ca-, and Mg-Exchanged (SWy-1 and SAz-1) Montmorillonite
Exchangeable Cation FTIR Hydration Hysteresis Smectite Sorption Water
2011/12/2
Abstract: An environmental infrared microbalance (EIRM) cell was used to study H2O sorption on two montmorillonite samples as a function of water content and type of exchangeable cation. The vibration...
An FTIR Study of Water Sorption on TMA- and TMPA-Montmorillonites
FTIR TMA-montmorillonites TMPA-montmorillonites Water Sorption
2011/12/1
Abstract: Water inhibits sorption of uncharged organic compounds on montmorillonites saturated with small alkylammonium cations such as tetramethylammonium (TMA) and trimethylphenylammonium (TMPA). As...
Synthesis of Highly Microporous and Hydrophilic Alumina-Pillared Montmorillonite: Water-Sorption Properties
Hydrophobicity Montmorillonite Pillared interlayer complex Porosity Surface condensation Thermal treatment X-ray powder diffraction
2012/1/4
A montmorillonite exchanged with large hydroxy-Al cations was thermally treated to convert the hydroxy cations to oxide pillars and to generate permanent microporosity in the interlayers. The pillared...
Thermodynamic and Structural Features of Water Sorption in Zeolites
Heulandite Stilbite Thermal stability Water sorption Zeolite
2012/2/10
The water adsorption capacity of zeolites is a function of pressure and temperature. Desorption of zeolites may be of three types, wherein the crystal lattice undergoes (1) no or little change, (2) a ...
