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 ... -
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 ... -
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 ... -
Microplastic contamination and characteristics spatially vary in the southern Black Sea beach sediment and sea surface water
(Elsevier, 2022)In this study, the abundance, and characteristics of the microplastics on the southern coast of the Black Sea were assessed. More than 70% of the detected microplastics were smaller than 2.5 mm and mostly consisted of ... -
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 ... -
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 ... -
Structural analysis of reactive dye species retained by the basic alumina surface
(Springer, 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 ... -
Yüzey aktif katyonlarla modifiye edilmiş Ünye bentonit ve tartrazin boyarmaddesi arasındaki etkileşimlerin XRD, TG/DTA, FTIR analiz tekniklerinin kullanılmasıyla ve adsorpsiyon verilerinin değerlendirilmesiyle incelenmesi
(Recep Tayyip Erdoğan Üniversitesi / Fen Bilimleri Enstitüsü / Kimya Anabilim Dalı, 2012)Bu çalışmada, setil piridinyum (SP) ve hekzadesiltrimetil amonyum (HDTMA) katyonik yüzey aktif maddelerle modifiye edilmiş Ünye bentonitler (SP- ve HDTMA-bentonitler) kullanılarak sulu çözeltilerden Tartrazinin uzaklaştırılması, ...
