Adsorption of Reactive Red 120 from aqueous solutions by cetylpyridinium-bentonite
Tabak, Ahmet; Baltaş, Nimet; Afşin, Beytullah; Emirik, Mustafa; Çağlar, Bülent; Eren, Erdal (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 of unye bentonite after treatment with sulfuric acid
Çağlar, Bülent; Afşin, Beytullah; Köksal, Engin; Tabak, Ahmet; Eren, Erdal (SOC Brasileira Quimica, 2013)Unye bentonite was found to consist predominantly of a dioctahedral smectite along with quartz, tridymite, cristobalite, and minor fractions of feldspar and anatase. A considerable amount of Al was retained as a constituent ... -
Covalent grafting of pyridine-2-methanol into kaolinite layers
Çağlar, Bülent; Çırak, Çağrı; Tabak, Ahmet; Afşin, Beytullah; Eren, Erdal (Elsevier, 2013)A novel hybrid organic-clay material was prepared by grafting of pyridine-2-methanol in the interlayer space of kaolinite by using a kaolinite/methanol compound as an intermediate. A kaolinite/methanol compound was obtained ... -
The spectral, structral and thermal characterizations of dimethyl sulphoxide, pyridine, ethanolamine and N-methyl formamide intercalated kaolinites
Çağlar, Bülent; Afşin, Beytullah; Eren, Erdal; Tabak, Ahmet; Çırak, Çağrı; Çubuk, Osman (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 ...
