Adsorption of lysozyme from aqueous solutions by a novel bentonite-tyrptophane (Bent-Trp) microcomposite affinity sorbent
Kalburcu, Tülden; Tabak, Ahmet; Öztürk, Nevra; Tüzmen, Nalan; Akgöl, Sinan; Çağlar, Bülent; Denizli, Adil (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 ... -
Characterization of AlFe-pillared Unye bentonite: A study of the surface acidity and catalytic property
Çağlar, Bülent; Çubuk, Osman; Demir, Ersin; Çoldur, Fatih; Çatır, Mustafa; Topcu, Cihan; Tabak, Ahmet (Elsevier Science Bv, 2015)Aluminium-iron-pillared bentonite has been prepared by incorporation of the iron mixed aluminium-polyoxocation into bentonite layers and characterized by the powder X-ray diffraction, Fourier transform infrared, thermal ... -
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 ... -

Tabak, Ahmet; Kaya, Mehmet; Yılmaz, Nurdane; Meral, Kadem; Önganer, Yavuz; Çağlar, Bülent; Sungur, O. (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 characterization of hexadecyltrimethylammonium-smectite composites and their potentiometric electrode applications
Çubuk, Osman; Çağlar, Bülent; Topçu, Cihan; Çoldur, Fatih; Sarp, Gökhan; Tabak, Ahmet; Şahin, Erdal (Elsevier, 2015)Organosmectites were prepared by the intercalation of hexadecyltrimethylammonium cations at various ratios into interlayer of Unye smectite. Structural, thermal, morphological and textural properties of the synthesized ... -
