Pyronin Y (basic xanthene dye)-bentonite composite: a spectroscopic study
(Elsevier Science Bv, 2014)
The expansion by 1.43 Angstrom of basal spacing and the shift to higher frequencies of in-plane ring vibrations of the Pyronin Y molecule at 1603 and 1527 cm(-1) on the formation of Pyronin Y-bentonite composite exhibited ...
Adsorption of lysozyme from aqueous solutions by a novel bentonite-tyrptophane (Bent-Trp) microcomposite affinity sorbent
(Elsevier, 2015)
This study deals with developing bentonite-tryptophan (Bent-Trp) microcomposite affinity sorbent (38-105 gm) for lysozyme adsorption from aqueous solutions. the structural analysis results of Bent-Trp microcomposites ...
Structural analysis of reactive dye species retained by the basic alumina surface
(2009)
The alumina-dye composites were prepared by treating the basic alumina with the water solutions of Reactive Red 120 (RR 120) and Reactive Blue 15 (RB 15) dyes. The bands of low intensities in the 1400-1600 cm-1 region and ...
The spectral, structral and thermal characterizations of dimethyl sulphoxide, pyridine, ethanolamine and N-methyl formamide intercalated kaolinites
(Verlag der Zeitschrift fur Naturforschung, 2010)
The intercalation of dimethyl sulphoxide (DMSO), pyridine (Py), ethanolamine (Ea), and Nmethyl formamide (NMF) molecules into the kaolinite interlayers led to an appreciable decrease of 3697 cm-1 of the hydroxyl band. The ...
Structural analysis of naproxen-intercalated bentonite (Unye)
(Elsevier, 2011)
The difference in the basal spacing (8.79Å) and a higher mass loss (6.2%) in the temperature range of 200-750°C of naproxen-bentonite (N-bentonite) comparing to that of Unye bentonite (UB) signified the existence of thermally ...
