摘要
通过对137Cs在两种粘土材料中的吸附与迁移行为的研究,探讨了粘土材料作为充填材料的可行性。用间歇法测定了两种粘土材料对137Cs的吸附比和吸附平衡时间,研究了粘土粒度材料特性和水相pH值对吸附比的影响,测定了吸附等温线及几种材料的吸附比。结果表明。
The sorption and migration of 137 Cs in two kinds of clay materials have been studied and the feasibility of clay as filling materials is discussed. The sorption ratio and equilibrium time for the two clay materials were measured with the intermittence method and the effects of clay grain size, materials property and water phase pH value on the sorption ratio was studied. And the sorption isothermal line was found to be a straight line. The results show that the two kinds of clay as filling materials of waste disposal can, to a certain extent, hinder the migration of 137 Cs.
