采用十八烷基硅胶小柱渗滤富集法从城市污水中提取直链烷基苯磺酸盐(LAS)、烷基酚聚氧乙烯醚(APEO)和壬基酚(NP)。采用反相高效液相色谱-紫外荧光检测法对样品进行定量。对生物处理后的废水进行分析，回收率在80%以上。该方法可快速、准确、可靠地测定浓度分别为20和4μg L−1的LASS和APEO。
An enrichment procedure involving percolation through octadecylsilica cartridges was applied to the extraction of linear alkylbenzenesulphonates (LASs), alkylphenol polyethoxylates (APEOs) and nonylphenol (NP) from treated and untreated municipal waste waters. The analytes were quantitated by reversed-phase high-performance liquid chromatography with UV-fluorescence detection. Recoveries higher than 80% were obtained from the analysis of biologically treated waste waters. The method allows rapid, precise and reliable determination of LASs and APEOs at concentrations as low as 20 and 4 μg l−1, respectively.
