Abstract This study is devoted to the ability of carbon fiber material samples impregnated with various amounts of barium iodide and triethylenediamine to remove radioactive methyliodide from air streams. The main sorption characteristics of impregnated UVIS® carbon fiber were determined and the use of this material for purifying of technological gas flows at nuclear power plants was evaluated. The methyliodide trapping efficiency by samples impregnated with barium iodide, TEDA, and their mixture was 83.4±0.8%; 93.1±0.6% and 93.5±0.7% respectively, under the same conditions. The study established a significantly higher capacity (8.3±0.07 mg/cm2) of samples impregnated simultaneously with both chemical compounds toward methyliodide. Under the same test conditions, the values of this parameter for the samples impregnated separately with TEDA and BaI2 were 2.85±0.05 mg/cm2 and 0.86±0.04 mg/cm2, respectively.

用浸渍的 UVIS® 碳纤维去除空气流中的放射性碘

摘要 本研究致力于研究用不同量的碘化钡和三亚乙基二胺浸渍的碳纤维材料样品从空气流中去除放射性甲基碘的能力。确定了浸渍的 UVIS® 碳纤维的主要吸附特性，并评估了这种材料在核电站技术气流净化中的用途。碘化钡、TEDA及其混合物浸渍的样品对甲基碘的捕集效率为83.4±0.8%；在相同条件下分别为 93.1±0.6% 和 93.5±0.7%。该研究建立了显着更高的容量 (8.3±0.07 mg/cm2)，同时用两种化合物浸渍的样品对甲基碘。在相同的测试条件下，
