BS ISO 7981-2-2005 水质.测定多核芳香烃类(PAH).液液萃取后用带荧光检测的高效液相色谱法测定六PAH
Water quality - Determination of polycyclic aromatic hydrocarbons (PAH) - Determination of six PAH by high-performance liquid chromatography with fluorescence detection after liquid-liquid extraction
This part of ISO 7981 specifies the determination of six selected PAH in drinking, mineral and table waters and ground and surface waters in mass concentrations above 0,005 μg/l, by high-performance liquid chromatography with fluorescence detection after liquid-liquid extraction. The six PAH are: fluoranthene, benzo[b]fluoranthene, benzo[a]pyrene, benzo[k]fluoranthene, indeno[1,2,3-cd]pyrene, and benzo[ghi]perylene (see Table 1). With some modification, this method is also applicable for the analysis of moderately polluted waste waters.
