摘要

用间歇法测定了１３７Ｃｓ在石湖峪和阳坊花岗岩上的吸附比和吸附平衡时间，研究了岩石颗粒度、固液比、水相ｐＨ值和核素载体浓度对吸附比的影响，测定了吸附等温线．用柱实验法研究了１３７Ｃｓ在石湖峪和阳坊碎石柱上的迁移行为，测定了阻滞因数和柱分配系数．结果表明：北京石湖峪和阳坊花岗岩对１３７Ｃｓ的吸附能力较差．

Abstract

The behaviors of sorption and migration of 137Cs on granites at Shiliuyu and Yangfang have been investigated by the batch technique and the column experiment.The sorption ratios m and sorption equilibrium time are determined. The effects of granite particle size

solid-to-liquid ratio

pH value of simulated groundwater

and Cs concentration on the Cs sorption ratio are studied. The migration of Cs in granite column are investigsted

and the distribution coefficient KD is determined. The results show that the ability of granites at Shihuyu and Yangfang to adsorb Cs is rather weak. Therafore high efficient backfill materials for Cs are necessary if depository is built on the base of granite.
