Surface Free Energy Components of Clay-Synthetic Humic Acid Complexes from Contact-Angle Measurements
Adsorption Aggregate stability Humic acid Montmoriltonite Surface free energy Wettability
2011/11/30
Abstract: The surface free energy components of clay-organic complexes were determined to assess to what extent an organic adsorbate modified the surface properties of the mineral, insofar as the stab...
Influence of Dodecylamine Chloride on the Surface Free Energy of Kaolinite
Contact angle Dodecylamine chloride Hydrophobicity Kaolinite Surface free energy
2011/11/30
Abstract: Contact angles of glycerol and diiodomethane drops were measured on the surface of kaolin pellets covered with different amounts of dodecylamine chloride (DDACl) to as much as one monolayer....
Influence of Exchangeable Cations on the Surface Free Energy of Kaolinite as Determined from Contact Angles
Contact angle Dispersion Kaolinite Surface free energy Wettability
2012/1/5
The influence of adsorbed H+, Na+, K+, Ca2+, Mg2+, Ba2+, and Al3+ ions on the wettability of a kaolinite surface was determined from contact angles, which were measured in kaolinite-water drop- air (s...
Determination of Surface Free Energy of Kaolinite
Adsorption Film pressure Free energy Kaolinite n-Octane Surface Water
2012/1/10
The adsorption of n-octane and water vapor on natural kaolinite was measured. From adsorption isotherms film pressures were determined which were then used to calculate the dispersion and nondispersio...
