【摘要】 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。更多还原

【Abstract】 The qualitative and quantitative analysis of hydrogen and carbon monoxide produced by radiation degradation of N,N-diethyl hydroxylamine is performed on a 2 m column packed with 5? (molecular) sieve and equipped with a thermal conductivity detector. The analysis of hydrogen employs argon as a carrier gas, the column temperature is 85 ℃ and the detector temperature is 110 ℃;the (analysis) of carbon monoxide employs hydrogen as a carrier gas,the column temperature is 50 ℃ and the detector temperature is 80 ℃. The results show that the volume fraction of hydrogen is increased with the increase of dose,but has little relationship with the concentration of N,N-diethyl hydroxylamine. Carbon monoxide is only produced when the absorption dose is very high and the volume fraction is very (low).更多还原
