摘要
建立了以二极管阵列检测器和荧光检测器串联的高效液相色谱分析方法,在标样未完全分离的情况下,采用双激发波长有效地改善了色谱分离条件。在设定的色谱条件下,各种多环芳烃(PAHs)的检出限为0.11～39.83μg/L,平均回收率为76.7%～98.3%,相对标准偏差为3.6%～12.6%。在南昌市布设4个环境空气采样点,测定PM10中PAHs含量。结果表明,八一广场、南昌市区二中老校区和罗家集区苯并(a)芘日均质量浓度最大值均超过《环境空气质量标准》(GB3095—1996)的限值,PAHs污染状况较严重。
A HPLC method was established,connected by the diode array detector and the fluorescence detec- tor,Completely has not separated in the standard sample in situation, to separate and detect the mixture of standard samples with double Excitation wavelength to effectively improve the chromatographic separation conditions. Under the set chromatographic conditions,the limits of detection of 16 PAHs varier from 0.11 μg/L to 39.83 μg/L,average recoveries range between 76.7 %-98.3% ,and the relative standard deviation between 3.6 %-12.6 %. Four atmospher- ic sampling points were built in Nanchang,Jiangxi povince and the PM10 samples were collected. The contents of PAHs in PM10 were detected by the above method. The results indicated that the maximal concentrations of Bap in the 8.1 square,the old campus of the Nanehang number 2 middle school and the Luojiaji surpassed the national standards,and the pollution situation is quite serious in Nanchang.
