水质.多核芳香烃类(PAH)的测定.第2部分:液液萃取后用带荧光探测的高效液相色谱法测定六PAH

[中文适用范围]： ISO 7981 的这一部分规定了通过液液萃取后采用荧光检测的高效液相色谱法测定饮用水、矿泉水和饮用水以及地下水和地表水中质量浓度高于 0.005 μg/l 的六种选定的 PAH。 这六种多环芳烃是：荧蒽、苯并[b]荧蒽、苯并[a]芘、苯并[k]荧蒽、茚并[1,2,3-cd]芘和苯并[ghi]苝（见表1）。 经过一些修改，该方法也适用于中度污染废水的分析。 [外文原描述]： ISO 7981-2:2005 specifies the determination of six selected PAH in drinking, mineral and table waters and ground and surface waters in mass concentrations above 0,005 micrograms per litre, 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. With some modification, this method is also applicable for the analysis of moderately polluted waste waters.
