摘要：

A new thermospray liquid chromatography/mass spectrometry (LC/MS) method for quantitative determination of trace levels of alcohol ethoxylates (AE) in dilute aqueous environmental samples has been developed. This method has been validated for use in aquatic safety assessments to determine concentrations of total AE and individual AE species. This validation was accomplished by determination of recoveries of spiked AE samples from waste treatment plant effluents and receiving waters. The method distinguishes highly branched propylene-based AE from isomeric linear ethylene-based AE.
