Sr、Cs 在回填材料中的吸附与迁移研究
THE STUDY OF ADSORPTION AND MIGRATION OF Sr and Cs IN BACKFILLING MATERIALS
【摘要】 以90Sr与137Cs为示踪剂,用静态与动态法研究了Cs、Sr在十几种地质材料中的吸附迁移行为,探讨了它们作为回填材料的可行性。结果表明:膨润土(新津产)对Sr、Cs,沸石对Cs的吸附能力很强,是好的回填材料。
【Abstract】 he adsorption of Sr and Cs in more than ten kinds of geologic material is studied with the tracers 90Sr and 137Cs. Adsorption ratio, adsorption equilibrium curve and adsorption equilibrium time of these materials to Sr and Cs, and influence of liquidphase acidity, particle size of material and solidliquid ratio on them are measured with hatch technique, and adsorption isothermal is also determined. Adsorption and migration of Sr and Cs in fine grained zeolite and bentonite column are studied by column experiment mthod. The result shows that bentonite from Xinjin Sichuan Province to Sr and Cs, and zeolite to Cs have a good adsorption performance, and are good backfilling material for the related nuclide waste, respectively.
