摘　　要：文章对两种进样方法测定水中甲醇进行了研究,对色谱条进行了优化.建立了静态顶空/直接进样气相色谱测定水中甲醇的方法.结果显示,两种方法的检出限分别为：0.14 mg/L和0.46 mg/L.回收率均能达到76.1％～102％之间.In the present work, the determination of methanol in water sample by two gas chromatography methods was investigated, and many factors were optimized. The new method of determination of methanol in aqueous sample was established followed by static headspace/direct injection gas chromatography. Finally, the detection limits of these two methods were 0.14 mg/L and 0.46 mg/L respectively. The recoveries of those methods were between 76 % and 102 %.
