摘要
建立了测定煤焦油中萘含量的填充柱气相色谱法。采用阿皮松填充柱(Φ3×2m)、氢火焰离子化检测器(FID),在恒温下,以正十二烷为萃取剂萃取煤焦油中的萘,对煤焦油中萘的含量进行了测定。结果表明,该方法具有良好的准确度和精密度,整个试样分析时间不超过20min,可直接用于产品的质量分析与控制,为焦化厂进行现场分析和操作调节提供了简捷理想的方法。
The naphthalene content in coal tar was analyzed by gas chromatography.A packed column(2m×3mm) was used with FID and at constant temperature.The naphthalene in coal tar was extracted with ndodecane.The experimental results are accurate and precise and the analysis time is less than 20min.The method can be used for product quality analysis and control.It is a simple and ideal method for on-site analysis and operational regulation.
