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...
Migration behaviour of barium and strontium through colemanite
Hatipoglu, S; Gokturk, H; Erten, HN (1996-01-01)
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.
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...
Adsorption of water and ammonia on TiO2-anatase cluster models
Önal, Işık; Senkan, Selim (2006-06-15)
Density functional theory (DFT) calculations performed at B3LYP/6-31G** level are employed to study water and ammonia adsorption and dissociation on (101) and (001) TiO2 anatase surfaces both represented by totally fixed and partially relaxed Ti2O9H10 cluster models. PM3 semiempirical calculations were also conducted both on Ti2O9H10 and Ti9O33H30 clusters in order to assess the effect of cluster size. Following dissociation, the adsorption of H2O and NH3 by H-bonding on previously H2O and NH3 dissociated s...
LEACHING BY FERRIC SULFATE OF RAW AND CONCENTRATED COPPER-ZINC COMPLEX SULFIDE ORES
BUTTINELLI, D; LAVECCHIA, R; POCHETTI, F; Geveci, Ahmet; GURESIN, N; Topkaya, Yavuz Ali (1992-10-01)
A composite mixture of three typical Cu/Zn complex ores, namely black-, yellow- and altered-ore, from Cayeli deposit in Turkey, was used for leaching experiments under atmospheric pressure in ferric sulphate solutions, In order to study the reaction kinetics of the copper and zinc dissolution in the temperature range from 50 to 80-degrees-C; also in the presence of a solvent for elemental sulphur, such as CCl4.
