气相谱法测定工业废气中的癸醇作者:王钢栋来源:《北方环境》2013年第07期 摘要:以活性炭吸附工业废气中的癸醇,用DB-624毛细管柱分离氢火焰离子化检测器检测,样品解析后直接进气相谱仪测定。当采样体积为20L,方法最低检出质量浓度为0.006 mg/m3活性炭采样管
,加标回收率在96.5%~102.7%%之间。方法简单、灵敏,分离度好、检出限低。 关键词:癸醇;工业废气;气相谱法

The adsorption of active carbon in industrial waste gas decanol, separation of hydrogen flame ionization detector using DB-624 capillary column, Determination of direct inlet chromatograph samples analysis. When the sampling volume was 20L, the minimum detectable concentration of 0.006 mg/m3, the recoveries were between 96.5% ~ 102.7%. The method is simple, sensitive, good resolution, low detection limit.Key words: Decanol; Industrial waste gas; Gas chromatography
