研究了￣（９０）Ｓｒ在沸石中的吸附与迁移行为，探讨了沸石作为回填材料的可行性。用间歇法测定了￣（９０）Ｓｒ在斜发沸石和丝光沸石等四组地质样品上的吸附比和吸附平衡时间，研究了沸石粒度、固液比和水相ｐＨ值对吸附比的影响，测定了吸附等温线，用柱实验法研究了￣（９０）Ｓｒ在粉碎沸石柱中的吸附与迁移行为。结果表明，沸石对￣（９０）Ｓｒ的吸附能力很强。
The adsorption and migration of ~ (90) Sr in zeolite were studied, and the feasibility of using zeolite as backfill material was discussed. The adsorption ratio and adsorption equilibrium time of ~ (90) Sr on four geological samples such as clinoptilolite and mordenite were determined by batch method. The effects of zeolite particle size, solid-liquid ratio and water phase pH on adsorption ratio were studied. The adsorption isotherms were determined. The adsorption and migration behavior of (90) Sr in the pulverized zeolite column was studied by column experiment. The results show that zeolite has strong adsorption capacity for (90) Sr.
