摘要

在TEDA(三乙二胺)浸渍活性炭床上研究了湿度对甲基碘吸附和解吸的影响。测定了碱浸渍活性炭和泰达浸渍活性炭在不同湿度条件下对碘化物的化学吸附量和物理吸附量。在水蒸气存在的情况下，甲基碘的物理吸附符合基于势理论的Dubinin-Radushkevich方程。即使在高湿度条件下，大量的化学吸附也证实了泰达浸渍永久捕获甲基碘化物的有效性。

Effect of water vapor on adsorption of methyl iodide to triethylenediamine-impregnated activated carbons

The effect of humidity on the adsorption and desorption of methyl iodide was investigated in a TEDA (triethylenediamine)-impregnated activated carbon bed. The amounts of chemisorption and physical adsorption of methyl iodide were measured in different humidity levels for base and TEDA-impregnated activated carbons. The physical adsorption of methyl iodide in the presence of water vapor was fitted with the potential theory-based Dubinin-Radushkevich equation. The significant amount of chemisorption even in high humidity conditions confirmed the effectiveness of TEDA-impregnation for trapping methyl iodide permanently.
