Infrared Spectroscopy Study of Tetrahedral and Octahedral Substitutions in an Interstratified Illite-Smectite Clay
Chourabi-Fripiat test Hofmann-Klemen effect Illite Infrared spectroscopy Interstratified Smectite Tetrahedral substitution
2011/12/28
Infrared spectroscopy is used to distinguish between octahedral and tetrahedral substitutions in an interstratified illite-smectite clay. The Hofmann-Klemen (Li) test suggests that the AlMg□ and FeMg□...
Identification of Noncrystalline (Fe,Cr)(OH)3 by Infrared Spectroscopy
Chromium hydroxide Goethite Infrared spectroscopy Iron hydroxide Noncrystalline Solid solution
2012/1/4
Iron-chromium hydroxides are important solid phases governing the aqueous concentrations of Cr(III) in soils and fly ashes. Although direct identification of noncrystalline (Fe,Cr)(OH)3 is difficult, ...
Contribution of Infrared Spectroscopy to the Study of Corrensite
Corrensite Exchangeable cation Hydroxyl Infrared spectroscopy Water
2012/2/2
A corrensite from Taro Valley, Italy, was studied by infrared analysis at different temperatures in the natural state and after exchange with seven different cations. The vibrational bands in the OH-s...
Infrared Spectroscopy of Picloram Interactions with Al(III)-, Fe(III)-, and Cu(II)-Saturated and Hydrous Oxide-Coated Montmorillonite
Adsorption Hydrous oxides Infrared spectroscopy Montmorillonite Picloram
2012/2/8
Thin clay films prepared from aqueous suspensions of the potassium or sodium salt of picloram (4-amino-3,5,6-trichloropicolinic acid) with Al-, Fe-, or Cu-saturated montmorillonite or with montmorillo...
Quantitative Estimation of Kaolinite in Sediments by Differential Infrared Spectroscopy
Hydroxyl Kaolinite Sediments
2012/2/10
An infrared method has been developed for estimating kaolinite in sediments. Hydroxyl stretching bands of kaolinite in sediments can be recorded by using a differential technique which eliminates the ...
