四氢化萘及萘烷均以萘为原料经催化加氢生成,常共存于工作场所空气中,笔者在检测中发现,GBZ/T 160.44—2004《工作场所空气中多环芳香烃化合物的测定方法》柱效低、操作繁琐,故建立了工作场所空气中萘及萘烷和四氢化萘的溶剂解吸-氢火焰离子化检测器-气相色谱法。在采样现场将打开熔封的活性炭管(管口直径至少2 mm,内装100、50 mg活性炭)与空气采样泵进气口垂直连接,以200ml/min流量采集15 min空气样品,活性炭管样品空白每组制备
Tetralin and decalin are naphthalene as raw materials by catalytic hydrogenation, often coexist in the workplace air, the author found in the test, GBZ / T 160.44-2004 “workplace air polycyclic aromatic hydrocarbons Determination ”Low column efficiency, cumbersome operation, so the establishment of the workplace air naphthalene and decalin and tetralin by solvent desorption - hydrogen flame ionization detector - gas chromatography. At the sampling site, a fused activated carbon tube (at least 2 mm in diameter with 100,50 mg of activated carbon) will be opened and connected vertically to the inlet of the air sampling pump to collect air samples at a flow rate of 200 ml / min for 15 min.
