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 ... -
