【摘要】 矿物对^１３４Ｃ_ｓ的吸附率与粒径之间的关系可用幂回归方程来表示；矿物能很快地吸附水体中的^１３４Ｃ_ｓ并达到吸附平衡；^１３４Ｃ＿ｓ水—吸附剂体系中的消失和吸附过程均遵循指数回归形式；沸石对^１３４Ｃ_ｓ的吸附能力最强，活化膨润土和珍珠岩较强，膨润土较弱；土壤也是一类良好的^１３４Ｃ_ｓ吸附剂；^１３４Ｃ_ｓ在土壤中的移动距离很小，有９５％左右集中在０—１ｃｍ的表土层中，淋溶水中只占１％以下；土壤对^１３４Ｃ_ｓ的吸附率与土层深度之间呈指数函数关系。更多还原

【Abstract】 There was a power regression between the adsorption rate of ￣(134)C_sby lnineral and the particle diameter.￣(134)C_s was strongly adsorded by mineral inwater phase and reached equilibrium. The variation of ￣(134)C_s in water min-eral system followed the form of exponential function. The adsorption abilityof ￣(134)C_s by mineral varied with specise:Zeolite>activated Bentonite>Pea-rlite>Bentonite,Soil was a effective kind of adsorbent of ￣(134)C_s.The migr-ation distance of ￣(134)C_s in soil was very small.95% radioactivity of ￣(134)C_s wasconcentrated in the surface soil and there was less than 1%in the leachate.The relation between the adsorption rate of ￣(134)C_s by soil and the deepnessof soil was represented with exponential regression.更多还原
