| 摘 要： | 本文用间歇平衡实验和柱迁移实验研究了放射性~(131)I~-和~(131)IO_3~-在花岗岩-1(浙江)、花岗岩-2(江苏)、紫色页岩(江苏)、凝灰岩(江苏)等4种地质材料中的吸附和迁移行为,并测定了它们的吸附比。结果表明,四种岩石样品对~(131)I~-和~(131)IO_3~-基本上不吸附或仅有微小的吸附,间歇平衡实验与柱迁移实验所得结果除紫色页岩相差稍大外,其它基本是一致的。 |

| Abstract: | both batch technique and column migration are used to investigate the sorption and migration behaviours of radioactive iodide and iodate on granite, tuff and violet shale, with 131I as a tracer.Migration velocity of iodide and iodate in column filled with geological materials is almost the same as that of the underground water front. The sorption ratio of iodide and iodate on these geological samples has been determined. The results show that there is no sorption or little sorption for I- and IO3- on various investigated rock samples. The results of batch technique agree with those of column migration experiment within the error limits. |
| Keywords: | Kadioactive iodine Geological material Column migration Sorption ratio. |
