摘要
介绍了碘吸附器的物理吸附、化学吸附和置换反应3种过滤机理。非放射性甲基碘CH_(3)^(127)I与放射性甲基碘CH_(3)^(131)I两种示踪剂在理化性质上一致,但在吸附机理上存在细微差别,设计实验探究CH_(3)^(127)I对碘吸附器的效率影响和进行核电厂碘吸附器定期效率实验的可行性,结合CH_(3)^(127)I相关检测方法与光电法优势分析确定下一步研究的方向。
Three filtration mechanisms of iodine adsorber,namely physical adsorption,chemisorption and displacement reaction,were introduced.The two tracers of non-radioactive methyl iodine CH_(3)^(127) I and radioactive methyl iodine CH_(3)^(131)I are consistent in physical and chemical properties,but there are subtle differences in adsorption mechanism.Experiments are designed to explore the effect of CH_(3)^(127) I on the efficiency of iodine adsorbers and the feasibility of conducting regular efficiency experiments of iodine adsorbers in nuclear power plants.Combining the advantages of CH_(3)^(127)I correlation detection method and photoelectric method,the next research direction is determined.
