The influence of chemical composition to position and intensity of the absorption bands observed in the FTIR spectra of palygorskite has been studied by a detailed comparative study of six samples. Pa...
Abstract: As a consequence of treatments with glycine solutions, glycine molecules enter the interlayer of both Ca- and Cd-rich montmorillonite. Measurements of d value suggest that at low glycine con...

Abstract: Water inhibits sorption of uncharged organic compounds on montmorillonites saturated with small alkylammonium cations such as tetramethylammonium (TMA) and trimethylphenylammonium (TMPA). As...
Abstract: Montmorillonites saturated with small quaternary alkylammonium ions such as tetramethylammonium (TMA) or trimethylphenylammonium (TMPA) are excellent sorbents for aromatic pollutants. In som...
Lawsonite single crystals were investigated by polarized FfIR spectroscopy at wave-numbers between 8000 and 1000 cm-1 and temperatures between 82 and 325 K.This temperature range contains three lawson...
In the critical comment byNathan (1996), the author essentially claims that the samples used in our study (Regnier et al. 1994) werenot very appropriate to dem-onstrate the absence of C03P-. Furthermo...
The carbonate substitution in apatite continues to pro-voke controversies. In a recent paper, Regnier etal. (1994) challenged the existence of the hypothetical C03P- ion in carbonate-fluorapatite (fra...
The substitution of Fe3+ in the kaolinite structure is studied by EPR spectrometry and by FTIR spectrometry on a large set of kaolins from different origins (sedimentary and primary ores, soil kaolins...
Abstract: Sorption of benzene onto Cu-montmorillonite was characterized by Fourier transform infrared (FTIR) spectroscopy and 13C magic angle spinning nuclear magnetic resonance (MAS NMR). Under anhyd...
Abstract: FTIR studies of six partially-deuterated montmorillonites (MS) reveal the presence of two O-D stretching bands, one between 2702–2728 cm-1 and another near 2680 cm-1. For homoionic (Li, Na, ...
