Clay-Organic Complexes as a Cementing Agent in the Arahama Sand Dune, Japan
Cementing agent Clay-organic complex Gel Sand dune Scanning auger multiprobe analysis Transmission electron microscopy X-ray photoelectron spectroscopy
2012/1/5
Cementing materials in the Arahama sand dune, Japan, were studied mineralogicaUy and biogeochemically to gain a better understanding of the cause of hardening. The cementing material is a clay- organi...
Adsorption and Desorption of N-Methyl 8-Hydroxy Quinoline Methyl Sulfate on Smectite and the Potential Use of the Clay-Organic Product as an Ultraviolet Radiation Collector
Adsorption Cation-exchange capacity N-methyl 8-hydroxy quinoline methyl sulfate Pharmaceutical Smectite Visible-ultraviolet spectroscopy
2012/1/5
The interaction between N-methyl 8-hydroxy quinoline methyl sulfate, a drug that absorbs erymathogenic near-ultraviolet radiation, and smectite was studied by X-ray powder diffraction (XRD) and adsorp...
Clay-Organic Complexes as Adsorbents for Phenol and Chlorophenols
Adsorption Chlorophenols Hydrophobicity Organo clays Phenol Smectite
2012/1/12
Several clay-organic complexes were synthesized by placing quaternary ammonium cations on smectite by cation exchange. They were then examined for their ability to adsorb phenol and several of its chl...
Clay-Organic Molecule Interactions: Oxidation of Acetaldehyde by Montmorillonite in N2 Atmosphere at Room Temperature
Acetaldehyde Acetate Adsorption Montmorillonite Oxidation
2012/2/10
Oxidation of acetaldehyde molecules adsorbed on Na- and Mg-Wyoming montmorillonite at room temperature (20–25°C) and in N2 atmosphere has been studied by I.R. spectroscopy. A comparison between clay-a...
A Natural Clay Organic Complex from Andalusian Black Earth
Natural Clay Organic Complex Andalusian Black Earth
2012/2/13
Protein complexes of smectites in soils are difficult to detect if the usual smectite tests show no peculiarities. Andalusian black earths are typical examples. Investigation of the alkylammonium deri...

2011/11/18
Abstract: Complexes of n-tetradecylammonium-beidellite with n-alkanols (n-C14H29NH3+)0,44(n-CxH2x + 1OH) 1,56{Mg0,28Al1,81(OH)2Si3,56Al0,44O10}0,44− (x = 8‒22) have been prepared and chara...
Mechanisms of Formation of Colored Clay-Organic Complexes. A Review
Mechanisms Formation Colored Clay-Organic Complexes Review
2012/2/20
The interactions of clay minerals with organic compounds which give rise to the formation of colored complexes, are discussed. The color reactions of clays can be ascribed to a charge transfer between...
Methylene Blue Absorption by Clay Minerals. Determination of Surface Areas and Cation Exchange Capacities (Clay-Organic Studies XVIII)
Methylene Blue Absorption Clay Minerals Cation Exchange Capacities
2012/2/20
Under appropriate conditions, both surface areas and cation exchange capacities of clay minerals can be measured by absorption of methylene blue from aqueous solutions. The method has been applied to ...
