| Abstract: | A novel rapid screening technique for the profiling of nonyl phenol ethoxylates (NPEs) in sewage treatment plant (STP) influent/effluent was developed using flow injection with atmospheric pressure ionization coupled to mass spectrometric analysis by combined precursor ion scanning and multiple reaction monitoring. The technique allows for total NPE concentrations as low as 50 parts-per-trillion to be detected in STP samples. |
