摘要
建立了顶空-毛细管气相色谱测定水中吡啶丙酮乙腈的方法,不用有机溶剂萃取和浓缩,减少了损失和对环境的污染,具有灵敏度高、检出限低、定量准确、操作简便等特点。当取样量为5ml时,检出限可达到0.006～0.03mg/L级,相对标准偏差为1.0%～2.3%,加标回收率在78.0%～100.2%之间,完全适合水中吡啶丙酮乙腈的测定。
Established Headspace-pyridine in water by capillary gas chromatography method of acetone,acetonitrile,Without organic solvent extraction and concentration,reducing losses and environmental pollution,A high sensitivity,low detection limit,accurate,easy to operate and so on.When the sampling volume of 5ml,the detection limit can reach 0.006 ～ 0.03mg /L level,The relative standard deviation of 1.0% ～ 2.3%,and the recovery at between 78.0% ～ 100.2%.Perfectly suited to water,acetone,acetonitrile and pyridine were determined.
