研究了~(134)Cs在沸石中的吸附与迁移行为.用间歇法测定了~(134)Cs(作为~(137)Cs的示踪剂)在斜发沸石和丝光沸石等4组地质样品上的吸附比(R_d);研究了接触时间、沸石颗粒度、固液比、pH值和核素浓度对吸附比的影响,测定了吸附等温线和铯的吸附容量.用柱实验法研究了~(134)Cs在沸石柱中的吸附与迁移行为,测定了~(134)Cs在柱中的迁移分布.结果表明,沸石对Cs的吸附能力很强,对Cs而言,沸石是核废物处置的很好的回填材料.
The adsorption and migration behavior of ~ (134) Cs in zeolites was studied, and ~ (134) Cs (as a tracer of 137 Cs) was determined by intermittent method in four geological samples such as clinoptilolite and mordenite (R_d). The effects of contact time, zeolite particle size, solid-liquid ratio, pH value and nuclide concentration on the adsorption ratio were investigated. The adsorption capacity of adsorption isotherms and cesium were determined. ~ (134) Cs in zeolite column, the migration and distribution of ~ (134) Cs in the column were measured.The results show that zeolite has a strong adsorption capacity for Cs, and for Cs, the zeolite is a nuclear waste Disposal of very good backfill material.
