紫外检测器-荧光检测器串联的HPLC法测定火力发电厂环境中的多环芳烃

 建立了一种紫外检测器(UVD)与荧光检测器(FLD)串联的HPLC法，检测了火力发电厂环境中的多环芳烃（PAH）化合物。在所选择的色谱条件下12个PAH可得到完全分离，其中萘等8个PAH用UVD检测，苯并〔a〕芘等4个PAH用FLD检测。应用该方法对湖南省内几家火力发电厂的废水、烟道气、粉煤灰中的12个PAH进行了实测，效果良好。

HPLC Determination of PAHs from Electric Power Plant by UVD-FLD Connected in Series

An HPLC method of UVD-FLD connected in series was used to detect naphthalene, biphenyl, fluorene, phenanthrene, anthracene, fluoranthene, 2-methyl-anthracene, chrysene, benzanthracene, benzfluoranthene b], benzfluoranthenek], benzopyrene PAH compounds in electricity plant environment. A CLC-ODS column (150 mm x 6.0 mm i.d.) with acetonitrile-water(85:15, V/V) as mobile phase and UV detector set at 250 nm and fluorescent detector set at lambda ex295 nm and lambda em427 nm were used. These 12 PAHs can be separated completely by this method. The earlier eluted eight PAHs were detected by UVD and the rest were detected by FLD. The minimum detectable concentrations of the 12 PAHs were 0.002 mg/L-0.1 mg/L. Satisfactory results were obtained in the analysis of PAH compounds in waste water, flue gas and flyash from several electric power plant in Hunan Province.
