【摘要】 该文用0.5 nm分子筛填充柱与热导型检测器(TCD)联用的气相色谱法定性定量分析了乙异羟肟酸水溶液辐解产生的氢气和一氧化碳.结果表明:当乙异羟肟酸浓度为0.1~0.5 mol/L、剂量为10~1 000 kGy时,氢气体积分数与乙异羟肟酸浓度的关系不大.当剂量低于500 kGy时,氢气体积分数随剂量增大而增大,但当剂量大于500 kGy时,氢气体积分数与剂量的关系不明显.一氧化碳只有在较高剂量时才产生,且体积分数很低.更多还原

【Abstract】 Qualitative and quantitative analyses of hydrogen and carbon monoxide produced from the radiolysis of AHA in aqueous solution are reported.Studies were performed using chromatography.A 2 m column packed with 0.5 nm molecular sieve and a thermal conductivity detector were used.The results show that volume fraction of hydrogen is very high when concentration of AHA is in the range of 0.1～0.5 mol/L and the dose is(10～1 000 kGy).Volume fraction of hydrogen is not closely related with AHA concentration.Volume fraction of hydrogen increases with the increase of dose when the dose is below 500 kGy,but is less dependent on the dose when the dose is higher than 500 kGy.Carbon monoxide is produced only when the dose is relatively high,and its volume fraction is very low.更多还原
