摘要
应用Levenberg—Marqurdt最优化方法,建立了直接测定工业甲醇中微量乙醇的气相色谱分析方法.结果显示,气相色谱法测定甲醇样品中微量乙醇具有准确度高、重现性好和操作简便等优点.本方法的相对标准偏差RSD〈2.06%（n=5）,加标回收率为95.20%~100.61%.
The paper was made gas chromatography of direct measurement infinitesimal ethanol in industrial methanol by us-ing optimum theory of Levenberg—Marqurdt. The results indicated that determining infinitesimal ethanol in industrial methanol by using gas chromatography had advantages of high accuracy, good reproducibility and user-friendly control. The relative standard deviation （RSD） of the method was 〈2.06% （n=5）, the recovery rate was 95.20% to 100.61%.
