post-column addition - Opis:
- Biodegradation of nonylphenol ethoxylates and dodecyl ethoxylates (C9H19-C6H4- -(OCH2CH2)n-OH and C12H25-(OCH2CH2)n-OH respectively) in river water in a static die-away test was performed. By using high performance liquid chromatography with electrospray ionization mass spectrometric detection (HPLC-ESI/MS), surfactants containing 2-4 ethoxylene units were detected as biodegradation products. Post-column addition of a number of metal cation was tested in order to improve the sensitivity of HPLC-ESI/MS analysis. Among the metal cations taken into account, the use of a lithium cation gave the best results provided that the cone voltage was increased to 40-50 V.
