摘要
用5A分子筛填充柱与热导检测器联用的气相色谱法定性定量地分析了甲异羟肟酸(FHA)水溶液辐解产生的氢气和一氧化碳.氢气的分析条件:以氩气作载气,柱温为85°C,检测器(TCD)温度为120°C;一氧化碳的分析条件:以氢气作载气,柱温为50°C,检测器(TCD)温度为80°C.研究结果表明氢气的体积分数随吸收剂量的增加而增大,但与FHA本身的浓度关系不大;一氧化碳只有在吸收剂量很高时才产生,而且体积分数很低.
This paper reports qualitative and quantitative analysis of hydrogen and carbon monoxide produced by γ-radiation degradation of aqueous formohydroxamic acid （FHA） solution by gas chromatography in which a packed 5A molsieve column and thermal conductivity detector（TCD） were used. Argon was used as a carrier gas in the analysis of hydrogen, with the column temperature 85 ℃, and the detector temperature 120 ℃, while hydrogen used in analysis of carbon monoxide, with the column temperature 50 ℃, and the detector temperature 80 ℃. The results show that volume fraction of hydrogen is increased with increasing dose, but has little relationship with concentration of formohydroxamic acid. Carbon monoxide is produced only at high dose, and the volume fraction is very low.
