摘要
本文提出了快速测定环境样品中强致癌物BaP的两波长定域同步荧光光谱法(SFDW),样品经有机溶剂超声提取后,可以不经过预分离而直接用于测定,该方法操作简单、快速、灵敏,分析一个样品的时间由原来的1小时缩短为几分钟。其检测限为10^(-10)g,定量的线性范围至少可达三个数量级,该方法直接检测BaP的结果和样品经过分离后,采用高效液相色谱法(HPLC)测定的结果相近,其相对误差小于±20％,易于实现仪器化。
A rapid method for the determination of Bap using the synchronous fluorescence spectroscopic scanning in defined range of dual wavelengths (SFDW) was developed. No presepara-tion for the samples under analysis is needed. The method proved to be simple, rapid and sensitive. The minimum detection limit of BaP is about 5×10-10g and the linear range is over three orders of magnitude, The average relative deviation is less than ± 20%. The results obtained with this method are comparable with those obtained with high performance liquid chromatography (HPLC).
