Correlation between Cation Exchange Capacity and Geotechnical Properties of Lateritic Soils.
Physical and chemical properties of most soils are influenced by their ion-exchange characteristics, including the amount and balance of individual ions present (Rayment and Lyons, 2011). Cation Excha...
Dispersive behaviour of soil clays has been explained by soil scientists using hypotheses involving various electrical diffuse double layer forces generated between colloidal clay particles suspended ...
For many purposes it is desirable to have a method for the determination of the cation exchange capacity of clay minerals based on principles as free from ambiguity as possible. Most of the many metho...
A series of novel superabsorbent nanocomposites were prepared by the solution radical polymerization of natural guar gum (GG), partially neutralized acrylic acid [sodium acrylate (NaA)], and cationex...
The OH speciation of 18 palygorskite samples from various localities were evaluated by near infrared spectroscopy (NIR) and compared to the corresponding octahedral composition derived from independen...
Abstract: The ammonium acetate saturation (AMAS) method was used to study the cation-exchange capacity (CEC) of zeolitic volcaniclastic materials from Santorini and Polyegos Islands, Greece. The AMAS ...
Abstract: Montmorillonites saturated with Li+, Na+, K+, NH4+, Mg2+, Ca2+, Ba2+, or Ni2+ ions can form complexes with propylene carbonate (PC) by intercalation; the d(001) of montmorillonite expands to...
A thermodynamic model of non-convergent cation-ordering in karrooite (MgTi O ) has been cali-2 5 brated from the single-crystal X-ray structure refinements of Yang and Hazen (1998) and from esti- ma...
Abstract: Sorption of several organic and inorganic cations on illite (Clay Minerals Society Source Clay Imt-2) was determined experimentally and results compared to model calculations. The cations st...
Non-convergent cation ordering in the (Fe O ) (MgAl O ) solid solution was investigated us- ing in-situ time-of-flight neutron powder diffraction. The approach to equilibrium in a sample with x = 0...
Abstract: Experimental cation exchange capacities (CEC) of kaolinites were determined and compared to theoretical calculations of CEC. The comparison reveals that the exchangeable cations occur mostly...

Abstract: We applied the hard and soft acid-base (HSAB) model (Xu and Harsh 1990a, 1990b) to bivalent cation exchange on a purified Ca-montmorillonite. As a result, a satisfactory model is proposed to...
The temperature dependence of the cation distribution in synthetic hercynite (FeAl2O4) has been determined using in-situ time-of-flight neutron powder diffraction. The sample was synthesized from the ...
