Abstract: [目的]建立工作场所空气中正戊醇溶剂解吸-气相色谱检测的方法。[方法]溶剂解吸-气相色谱法,以正丁醇-二硫化碳溶液(体积比1∶100)作为解吸液,采用0.32 mm×30 m FFAP毛细管气相色谱柱、氢火焰离子化检测器(flame ionization detector,FID)对正戊醇进行检测。[结果]本方法正戊醇的检出限为1.3μg,相关系数r>0.999,精密度为2.4%~7.7%,不同浓度回收率在96.1%~101.1%之间,采样效率100%,解吸效率为92.3%,正戊醇穿透容量>6.1 mg;样品在常温下可保存7 d。[结论]该方法操作方便,准确可靠,可以用于工作场所空气中正戊醇的测定。
