Characterization and pillaring of a Turkish bentonite (Resadiye)
Tabak, Ahmet; Afsin, B.; Çağlar, B.; Köksal, E. (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 characteristics of organo-modified bentonites of different origin
Tabak, A.; Afşin, B.; Aygün, S.F.; Köksal, E. (Springer, 2007)Organobentonites were synthesized by treating Na-bentonites (Wyoming and Reşadiye) with cetylpyridinium chloride (CPC) using ion exchange method. The difference in the basal spacing by 0.65 Å and a higher mass loss by ... -
Structural characterization of aniline-bentonite composite by FTIR, DTA/TG, and PXRD analyses and BET measurement
Köksal, E.; Afşin, B.; Tabak, Ahmet; Çağlar, B. (Taylor & Francis, 2011)The aniline species incorporated into the acid-activated bentonite matrices leads to the decay of the skeletal stretches centered at 1041 cm-1 and the rise of new features in the phenyl ring frequency region, 1700-1400 ...
