Effects of Exchangeable Cations on Hydraulic Conductivity of a Marine Clay
Consolidation Dispersion Exchangeable cation Hydraulic conductivity
2011/12/28
A laboratory study of the hydraulic conductivity (HC) of a marine clay with monovalent, divalent and trivalent cations revealed large differences in HC. The exchangeable cations employed in this study...
Use of Methylene Blue and Crystal Violet for Determination of Exchangeable Cations in Montmorillonite
Cation exchange capacity Crystal violet Exchangeable cations ICP Methylene blue Montmorillonite Organic cations
2012/1/4
A procedure for the determination of cation exchange capacity (CEC) and the amounts of exchangeable cations adsorbed to montmorillonite is proposed. The method consists of a single incubation of the c...
57Fe Mossbauer Spectroscopic Study of Structural Changes During Dehydration of Nontronite: Effect of Different Exchangeable Cations
Mossbauer Dehydration Nontronite Cation migration Tetrahedral site
2012/1/4
Dehydration-induced migration of different exchangeable cations toward the layers of nontronite has been studied by M鰏sbauer spectroscopy. As interlayer water is removed exchangeable cations migrate t...
The Effect of Heat Treatments on the Total Charge and Exchangeable Cations of Ca-, Na-, and Li-Saturated Kaolinite
Kaolinite Cation exchange capacity Water adsorption Lithium retention
2011/12/31
The effect of heat treatments on the total charge and water adsorption by Ca-, Na- and Li-saturated kaolinite was studied using extraction techniques and thermal gravimetric analysis, respectively. Me...
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...
The Effect of Exchangeable Cations on the Sorption of Chlorophyllin by Montmorillonite
Effect Exchangeable Cations Sorption Chlorophyllin Montmorillonite
2012/2/20
The sorption of commercial K-Cu chlorophyllin by a sample of montmorillonite saturated with different exchange ions was studied. The organic anions are sorbed on external surfaces while K displaces mo...
Measurement of Exchangeable Cations in Bentonites
Measurement Exchangeable Cations Bentonites
2012/2/21
High swelling bentonites cannot be analyzed for exchangeable cations with exactly the same technique as most soils. To resolve varied techniques used in the past and to establish a reliable procedure,...
X-ray Diffraction Band Profiles of Montmorillonite—Influence of Hydration and of the Exchangeable Cations
X-ray Diffraction Band Profiles Montmorillonite Hydration
2011/11/16
Previous studies of diffraction band profiles of montmorillonite are extended to the 13, 20 band which, for reasons discussed, is more sensitive to structural details than the diffraction bands consid...
