Equilibrium desorption isotherms of water, ethanol, ethyl acetate, and toluene on a sodium smectite clay
Clay Dynamic vapour sorption Ethanol Ethyl acetate Knudsen thermogravimetry Smectite Sorption isotherm Toluene Water
2011/11/10
Abstract Desorption isotherms for water, ethanol, ethyl acetate and toluene from a sodium smectite clay have been determined by both dynamic vapor sorption (DVS) measurements and Knudsen thermogravim...
Investigation of Adsorption Isotherms of Myristic, Palmitic and Stearic Acids on Rice Hull Ash
Adsorption free energy of adsorption Langmuir isotherm myristic, palmitic stearic acids rice hull ash
2010/6/28
The adsorption of myristic, palmitic and stearic acids on rice hull ash from isooctane as solvent was studied and conformed to a Langmuir isotherm. Monolayer coverage was determined to be 40.08, 38.43...
The Adsorption Isotherms of the Bleaching of Sun ower-Seed Oil
Adsorption isotherm bleaching Freundlich equation Langmuir equation sunflower-seed oil
2010/7/1
In this study, the absorbance measurements were taken for the bleaching of sunflower-seed oil with wt. 0.3, 0.5, 0.7 and 0.9 % of clay at 60, 70, 80 and 90°C. Bentonite EY-09 was used as the bleaching...
Effect of Negative Surface-Charge Densities of Smectite Clays on the Adsorption Isotherms of Racemic and Enantiomeric Tris(2,2′-Bipyridyl)Ruthenium(II) Chloride
Adsorption Enantiomorphs Racemic pairs Smectite Surface charge Tris(2,2′-bipyridyl)ruthenium(II)
2012/1/5
The level of adsorption of enantiomeric tris(2,2′-bipyridyl)ruthenium(II) (Ru(bpy)32+ by seven different smectite samples was found to be controlled by the total surface area of the clay. The level co...
