Adsorption of Reactive Red 120 from aqueous solutions by cetylpyridinium-bentonite
Tabak, Ahmet; Baltas, Nimet; Afsin, Beytullah; Emirik, Mustafa; Caglar, Bulent; 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
Caglar, Bulent; Afsin, Beytullah; Koksal, 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
Caglar, Bulent; Cirak, Cagri; Tabak, Ahmet; Afsin, 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 ... -
Flow Injection Potentiometric Determination of Silver(I) in Photographic Film Developing Solution Samples by Polyvinylchloride Membrane Silver(I) Selective Electrode
Topcu, Cihan; Coldur, Fatih; Andac, Muberra; Cubuk, Osman; Kanberoglu, Gulsah Saydan; Caglar, Bulent; Isildak, Ibrahim (Chem Soc Pakistan, 2016)A polyvinylchloride (PVC) membrane silver(I) selective electrode was developed for the determination of silver(I) ions in photographic film developing solutions. The electrode was embedded into a home-made flow cell and ... -
