Adsorption of ammonium (NH4+) from aqueous solution by Unye bentonite
(Foundation Environmental Protection & Research-Fepr, 2013)
In this study, ammonium (NH4+) removal from aqueous media was investigated by using bentonit clay. Different concentrations of ammonium ion adsorption from aqueous solutions were examined at a room temperature. Adsorption ...
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 ...
Characterization and pillaring of a Turkish bentonite (Resadiye)
(Elsevier, 2007)
The shifts of the Si{single bond}O{single bond}Si stretching and the Si{single bond}O{single bond}Al and Si{single bond}O{single bond}Si bending modes, as well as the free silica peak in the IR spectra and the strengthening ...
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 ...
Adsorption of Reactive Red 120 from aqueous solutions by cetylpyridinium-bentonite
(Wiley, 2010)
BACKGROUND: The removal of Reactive Red 120 (RR 120) from aqueous solutions using cetylpyridinium modified Resadiye bentonite (CP-bentonite) prepared by ion exchange was investigated with particular reference to the effects ...
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 ...
