摘要：A method was developed for the determination of nonionic polyoxyethylene surfactants in low concentration (0.2-1.0 ppm) by atomic absorption spectrophotometry. This method is based on the bismuth contained in the precipitate which is produced by nonionic polyoxyethylene surfactants and modified Dragendorff reagent. It was possible to determine 0.02 mg of the surfactant in 11 of the sample when the foam separation method and ion-exchange resin column chromatography were used for the concentration and purification of the sample. The sensitivity of this method is about 10 times higher than that of ammonium tetrathioisocyanatocobaltate. This method was used to detect nonionic polyoxyethylene surfactants in the waste water from apartment houses.
