报道了用三氧化二铝毛细柱与氢火焰离子化检测器联用的气相色谱法,定性定量分析了N,N-二甲基羟胺水溶液辐解产生的气态烃类。结果表明,辐照剂量为10—1000kGy时,N,N-二甲基羟胺水溶液辐解产生的气态烃类有甲烷、乙烷、乙烯、丙烷、丙烯和正丁烷,当N,N-二甲基羟胺浓度为0.2mol/L时,甲烷的体积分数为9.996×10-6—247.5×10-6,乙烷、丙烷和正丁烷的体积分数较低,而乙烯和丙烯的体积分数则更低。甲烷的体积分数随剂量的增加而增加,而乙烷、乙烯、丙烷、丙烯和正丁烷的体积分数随剂量变化不明显。
A gas chromatographic method using alumina capillary column with flame ionization detector was reported to qualitatively and quantitatively analyze the gaseous hydrocarbons produced by the radiolysis of N, N-dimethylhydroxylamine aqueous solution. The results showed that the gaseous hydrocarbons produced by the radiolysis of N, N-dimethylhydroxylamine aqueous solution were methane, ethane, ethylene, propane, propylene and n-butane at irradiation dose of 10-1000kGy. When N, N- When the concentration of hydroxylamine was 0.2mol / L, the volume fraction of methane was 9.996 × 10-6-247.5 × 10-6, the volume fraction of ethane, propane and n-butane was lower, while the volume fraction of ethylene and propylene was lower . The volume fraction of methane increased with dose, but the volume fraction of ethane, ethylene, propane, propylene and n-butane did not change with dose.
