摘要
用动态柱实验法和静态批式法研究了放射性锶在凝灰岩中的吸附和迁移。凝灰岩产自河北省,粒度为60—120目。用静态批式法测定的锶的吸附比 R_d 值为64 mL·g^(-1);动态柱实验法测得的阻滞因数 R_f 值为290,计算得到的 R_d 值为130 mL·g^(-1)。
The migration behavior of Sr in tuff was studied in both batch and column experiments.The tuff sample which was drawn from Hebei Province was of size range of 60—120 mesh.TheSorption ratio(R_d)of Sr obtained in batch experiments was 63 mL·g^(-1).In column experimentsretardation factor(R_f)measured was 289.7,from which the R_d value was calculated to be 129.9 mL·g^(-1).The value is higher than that obtained in batch experiments.
