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 micrograms l-1, respectively.
一种通过十八烷基硅胶柱渗滤的富集方法被用于从经处理和未经处理的城市废水中提取直链烷基苯磺酸盐（LASs）、烷基酚聚乙氧基化物（APEOs）和壬基酚（NP）。通过具有紫外-荧光检测的反相高效液相色谱法对分析物进行定量。对经过生物处理的废水分析获得了高于80%的回收率。该方法能够分别快速、精确且可靠地测定浓度低至20微克/升和4微克/升的LASs和APEOs。
