Column and batch experiments were performed to study the migration behaviour of Ba and Sr in colemanite matrix. Ba-133, Sr-90 and H-3 were used as tracers. The retardation factors and the distribution ratios of Ba and Sr in column experiments were found to be smaller than those obtained in batch experiments. Sorption R(d) values of Ba were higher than those of Sr determined by both techniques. Sorption energies calculated from batch experiments are in good agreement with the literature values.

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...
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.
Sorption of barium on kaolinite, montmorillonite and chlorite
Eylem, Cahit; Erten, Hasan N.; Göktürk, Hale (Royal Society of Chemistry (RSC), 1989)
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 Dubin...
Confinement Effectiveness of CFRP in Axial Members under Various Loading Conditions
ERDİL, BARIŞ; Akyüz, Uğurhan; Yaman, İsmail Özgür (2013-07-17)
In this study, parameters affecting the mechanical properties of FRP-confined cylindrical and prismatic concrete columns were studied via experimental data, which were collected after an extensive literature review. The parameters were summarized as unconfined concrete strength, FRP thickness, cylinder diameter, overlap length of FRP, sustained stress level, heating-cooling effect and corner radius in prismatic specimens. Considering these parameters the confinement effectiveness is established analytically...
Activity Comparison of Different Solid Acid Catalysts in Etherification of Glycerol with tert-Butyl Alcohol in Flow and Batch Reactors
Ozbay, Nalan; OKTAR, NURAY; DOĞU, GÜLŞEN; Doğu, Timur (2013-12-01)
In the presented work, etherification of glycerol with TBA was investigated in a continuous flow and also in a batch reactor using nine different commercial solid acid catalysts, namely Amberlyst-15, Amberlyst-36, Amberlyst-35, Amberlyst-16, Relite EXC8D, Lewatit K2629, H-Beta, H-Mordenite and Nafion SAC-13. Results proved the advantages of flow reactor to achieve quite high glycerol conversion values in very short residence times, due to efficient contact of reactants with the solid catalyst, which was cau...
