The coordination numbers of Na and K atoms in low albite and microcline as determined from a procrystal electron-density distribution
The coordination numbers Na and K atoms low albite microcline electron-density distribution
2012/4/9
Procrystal modelsfor the electron-density distributions oflow albite and microcline were constructed by placing spherically averaged Clementi-Roetti atomic wave functions at ex-perimentally observed a...
Synthesis and CO2 Adsorption Features of a Hydrotalcite-Like Compound of the Mg2+-Al3+-Fe(CN)64- System with High Layer-Charge Density
Al3+-substitution CO2 adsorption Hydrotalcite-like compound Ion exchange
2011/12/30
Hydrotalcite-like compounds (HT) with 24%–48% Al3+-substitution have been synthesized in the Mg2+-Al3+-Fe(CN)64- system. Conditioning of the synthesized and air-dried compound with K4Fe(CN)64- solutio...
Charge Density and Na-K-Ca Exchange on Smectites
Cation exchange Charge density Selectivity coefficient Smectite Swelling
2011/11/25
Abstract: Ca-K-, Na-K-, and Ca-Na-exchange isotherms on four reference smectites were studied. The electric charge on the four smectites was due predominantly to cationic substitution in the octahedra...
Optical Density of Vertisol Clay Suspensions in Relation to Sediment Volumes and Dithionite-Citrate-Bicarbonate-Extractable Iron
Beidellite Extractable Fe Fabric Optical density Tactoid Vertisol
2012/1/11
Clay fractions of eight vertisols and vertisolic soils from Israel were found to consist principally of a Fe-rich beidellite. Sediment volumes of Na-clay suspensions, obtained in measuring cylinders a...
Surface Charge Density Determination of Micaceous Minerals by 235U Fission Particle Track Method
Micaceous Minerals 235U Fission surface charge density mica
2012/2/13
The surface charge density of mica (001) cleavages was determined by counting the number of fission particle tracks in a given area of a 6-mm muscovite disc replica with optical and scanning electron ...
Heterogeneity of Charge Density Distribution in Montmorillonite as Inferred from Cobalt Adsorption
Heterogeneity Charge Density Distribution Montmorillonite Cobalt Adsorption
2011/11/18
Abstract: A comparison is made of the ion exchange behavior, towards the cobalt ion, of five sodium montmorillonite clays. The selectivity for the bivalent ion at low cobalt loading is correlated with...
Particle Geometry and Optical Density of Clay Suspensions
Particle Geometry Optical Density Clay Suspensions
2012/2/20
Data on montmorillonite and illite collected by A. Kahn were further analyzed to show the relationship between particle geometry and the optical density (OD) of the clay suspensions. A correction was ...
