用5 分子筛填充柱与热导型检测器联用的气相色谱法,定性定量分析了N,N 二乙基羟胺水溶液辐解产生的氢气和一氧化碳。分析氢气时,以氩气为载气,柱温为85℃,检测器温度为110℃;分析一氧化碳时,以氢气为载气,柱温为50℃,检测器温度为80℃。研究结果表明:氢气的体积分数随着吸收剂量的增加而增加,而与N,N 二乙基羟胺浓度的关系不大;一氧化碳只有在很高吸收剂量时才产生,且体积分数很低。
The gas chromatograph of 5 molecular sieve packed column and thermal conductivity detector was used to qualitatively and quantitatively analyze the hydrogen and carbon monoxide produced by the radiolysis of aqueous N, N diethylhydroxylamine solution. When hydrogen was analyzed, argon was used as the carrier gas. The column temperature was 85 ° C and the detector temperature was 110 ° C. When carbon monoxide was analyzed, hydrogen was used as a carrier gas. The column temperature was 50 ° C and the detector temperature was 80 ° C. The results show that the volume fraction of hydrogen increases with the increase of absorbed dose, but not with the concentration of N, N diethyl hydroxylamine. The carbon monoxide is only produced at very high absorbed dose, and the volume fraction is very low.
