    Migration behaviour of Barium and Strontium in Granite
    (De Gruyter Oldenbourg, 1994-12-01) Hatipoğlu, S.; Göktürk, H.; Erten, H. N.
    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 behaviour of barium and strontium through colemanite
    (De Gruyter Oldenbourg, 1996) Hatipoǧlu, S.; Göktürk, H.; Erten, H. N.
    Column and batch experiments were performed to study the migration behaviour of Ba and Sr in colemanite matrix. 133Ba. 90Sr and 3H 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 Ra 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.
