Linear 4-alkylbenzenesulfonates (LAS), 4-alkylphenol polyethoxylates (APEO) (i.e., 4-octylphenol polyethoxylates (OPEO) and 4-nonylphenol polyethoxylates (NPEO), and 4-nonylphenol (NP) are simultaneously determined by reversed-phase high-performance liquid chromatography (HPLC) using octylsilica columns and water/acetonitrile gradient elution. LAS are separated according to their alkyl chain lengths and coelution of NPEO and NP is observed in contrast to the separation of OPEO and NPEO. The determination of oligomer distributions of APEO and quantitation of NP,NP1EO, and NP2EO require additional information attainable by normal-phase HPLC. Recoveries of 85-100% were found for LAS, APEO, and NP isolated by Soxhlet extraction under basic conditions from laundry detergent powders, sewage sludges, sludge-amended soils, and river sediments. Relative standard deviations for all analytes in the different matrices did not exceed 6%. Detection limits with UV fluorescence detection are 95 ng for NP, 80 ng for LAS, and 65 ng for NPEO with respect to injected amounts.
