摘　　要：研究建立了气相色谱法同时测定水中吡啶、松节油和苯胺的方法。采用二氯甲烷萃取,萃取后直接进行色谱分离分析,3种物质能够有效分离。吡啶、松节油和苯胺的水中最低检测浓度分别为0.009、0.009、0.004mg/L,样品添加平均回收率为89%～114%,平行6次精密度实验,相对标准偏差小于6.5。实验结果表明,气相色谱法简单、快速、准确,适用于水中吡啶、松节油和苯胺的测定。The establishment of a gas chromatographic spectrum method for the determination of aniline,Turpentine oil and pyridine in water is described.The 100ml water sample was extracted with 10ml dichloride methane.The compounds were separated from each other through SPB-608 capillary column（30m×0.53mm×0.50μm） and then determined by GC-FID.The average recoveries and relative standard deviations of aniline,Turpentine oil and pyridine were 89%~114% and less than 6.5% respectively.These results demonstrate that the gas chromatographic spectrum method is simple,fast,sensitive and accurate for aniline、Turpentine oil and pyridine determination of Complicated of water samples.
