摘　　要：以N,N—二甲基乙酰胺为溶剂,正十四烷为内标物,对循环柴油萘的含量进行了测定,样品的回收率在99.18%~104.52%,循环柴油样品萘含量的相对标准偏差RSD为2.14%~3.03%,整个试样分析时间不超过30min,为国内焦化行业进行现场分析和操作调节提供了简捷理想的方法。The internal standard method is adopted to determine the naphthalene content in the diesel by using chloro- benzene as a solvent and normal dodecane as internal standard. The recovery rate of naphthalene in the diesel is 99.18% --104.2% and relative standard deviation is 2.14% ~ 3.03%. The total analysis time is not more than 30 min. This pro- vides a ideal method for the domestic coking industry scene analysis and simplicity of operation regulation
