Water samples were collected at two polluted rivers and near the discharge mouth of a large secondary wastewater treatment plant in Tokyo. After surfactants in filtrates were adsorbed onto Amberlite XAD‐16 resin and eluted with methanol, the co‐adsorbed anionic and cationic surfactants in the eluent were removed with a strong cation‐ and anion‐exchange resin column. Poly(oxyethylene) octylphenyl ether nonionic surfactant was separated using normal‐phase high‐performance liquid chromatography (HPLC) with UV detection at 280 nm and a pure carbon column after concentration of the eluent by nitrogen gas stream. A relatively large unknown peak in the HPLC chromatogram was fractionated and an attempt was made to identify it by atmospheric pressure chemical ionization and electrospray ionization mass spectrometry. The present study tentatively identified the occurrence of persistent poly(glycidyl) monofluorooctylphenyl ether nonionic surfactants as one of the new persistent organic pollutants in river waters and effluent from a secondary wastewater treatment plant.
