用气相色谱法测定工业冷却废水中微量甲醇、乙醇、丙酮、醋酸甲酯、醋酸乙烯的含量

Detecting the Content of Trace Methanol,Ethanol,Acetone,Methoxycarbonyl Acetate,Vinyl Acetate from Industrial Cooling Wastewater with Gas Phase Chromatography Method

该文提出了以正丙醇为内标 ,GDX— 10 1高分子多孔微球为柱填料 ,用氢火焰检测器测定 ,使用 10 2 G- D气相色谱仪 ,可测出低至 1mg/ L的甲醇、乙醇、丙酮、醋酸甲酯和 10 m g/ L的醋酸乙烯。

The article puts forward the detecting method of using r-propyl alcohol as internal standard,using GDX-101 polymer porasil as column filling,using 102G-D gas phase chromatography and hydrogen flame detector.The result shows that the method can detect the methanol,ethanol,Acetone,methoxycarbonyl acetate which content are below to lmg/l and vinyl \{acetate\} which content is below to 10mg/l.
