MIGRATION BEHAVIOR OF BARIUM AND STRONTIUM IN GRANITE

The sorption behaviour of Ba2+ and Sr2+ cations on granite have been s tudied under flowing and static conditions in column and batch experim ents. Ba-133, Sr-90 and H-3 were used as radio tracers. The retardatio n 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 gra nite than strontium. Sorption energies were found to be in good agreem ent with literature values.
