【摘要】 建立了顶空气相色谱法测定γ辐照三烷基氧膦中微量轻质烃的方法。研究了色谱条件及顶空加热条件。方法的回收率为 90 %— 10 9% ,对正戊烷、正己烷、正辛烷的检出限分别为 8.7× 10 - 7、3.2× 10 - 6 、3.1× 10 - 5g/ m L。用于测定三烷基氧膦中轻质烃辐解产物得到满意的结果更多还原

【Abstract】 A method for determination of hydrocarbons by head\|space gas chromatography was developed.The chromatographic conditions and effects of head space conditions on peak height were studied.The experimental results indicate that the recovery of the method is 90%-109%.The detection limits for n \|pentane, n \|hexane, n \|octane is 8.7 ×10 -7 ,3.2×10 -6 ,3.1×10 -5 g/mL,respectively.The method has been applied to determination of radiolysis products in TRPO with satisfactory results.更多还原
