The sorption characteristics of the Ba2+ ion on kaolinite, montmorillonite and chlorite type clays were studied using the batch method. Barium-133 was used as a tracer. The Ba2+ ion concentrations ranged from 10–8 to 10–5 mol l–1; synthetic groundwater was used and the grain size of all the solid particles was <40 µm. About 6, 8 and 12 d of shaking were necessary to reach equilibrium for chlorite, kaolinite and montmorillonite, respectively. The sorption isotherms were described best by Freundlich and Dubinin-Radushkevich type isotherms. Sorption was predominantly reversible for kaolinite and partly reversible for montmorillonite and chlorite.

Migration behaviour of barium and strontium in granite Hatipoglu, S; Gokturk, H; Erten, HN (1993-12-17) The sorption behaviour of Ba2+ and Sr2+ cations on granite have been studied under flowing and static conditions in column and batch experiments. 133Ba, 90Sr and 3H were used as radio tracers. The retardation factors, R1, and distribution ratios, Rd, of barium and strontium in column experiments were found to be smaller than those from batch experiments. In both techniques barium was sorbed more strongly on granite than strontium. Sorption energies were found to be in good agreement with literature val-ues.
MIGRATION BEHAVIOR OF BARIUM AND STRONTIUM IN GRANITE HATIPOGLU, S; GOKTURK, H; ERTEN, HN (1994-01-01) The sorption behaviour of Ba2+ and Sr2+ cations on granite have been studied under flowing and static conditions in column and batch experiments. Ba-133, Sr-90 and H-3 were used as radio tracers. The retardation factors, R(f) and distribution ratios, R(d), of barium and strontium in column experiments were found to be smaller than those from batch experiments. In both techniques barium was sorbed more strongly on granite than strontium. Sorption energies were found to be in good agreement with literature va...
Dimethyl ether from syngas and effect of CO2 sorption on product distribution over a new bifunctional catalyst pair containing STA@SBA-15 ÇELİK ÖZCAN, MERVE; PEKMEZCİ KARAMAN, BİRCE; OKTAR, NURAY; Doğu, Timur (2022-12-01) Direct synthesis of dimethyl ether (DME) from syngas was investigated in the presence of a bifunctional catalyst pair containing silicotungstic acid (STA) incorporated SBA-15 (5, 10, 25% by wt. STA) for the in-situ dehydration of synthesized methanol. The methanol synthesis component of this catalyst mixture is a Cu/ZnO-based commercial (HF) catalytic material. The new STA@SBA-15 type solid acid catalysts synthesized in this study indicated ordered mesoporous structures with surface area values in the range...
Sorption of radioactive cesium and barium ions onto solid humic acid Celebi, O.; Kilikli, A.; ERTEN, HASAN NİYAZİ (Elsevier BV, 2009-09-15) In this study, the sorption behavior of two important fission product radionuclides ((137)Cs and (140)Ba) onto sodium form of insolubilized humic acid (INaA) were investigated as a function of time, cation concentration and temperature, utilizing the radiotracer method. The sorption processes are well described by both Freundlich and Dubinin-Radushkevich type isotherms. Thermodynamic constants such as: free energy (Delta G(ads)), enthalpy (Delta H(ads)), entropy (Delta S(ads)) of adsorption were determined....
Asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohol derivatives and applications in various asymmetric transformation reactions Odabaş, Serhat; Tanyeli, Cihangir; Department of Chemistry (2007) The asymmetric synthesis of N-aryl substituted chiral 1,4-aminoalcohols and their applications in asymmetric borane reduction and enantioselective diethylzinc addition to benzaldehyde reactions were performed starting from meso-anhydride 51 that is the cycloadduct of cyclopentadiene and maleic anhydride. The desymmetrization of meso-anhydride 51 was achieved by using quinine or quinidine with very high enantiomeric excess value (up to 98% ee) and with high chemical yield. The quinine-mediated desymmetrizati...
