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 (Sociedade Brasileira de Química, 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 interlayerspace of kaolinite by using a kaolinite/methanol compound as an intermediate. A kaolinite/methanolcompound was obtained ...
