This paper presents a method for the determination of alkylphenols, alkylphenol
polyethoxylates (APEO) and alkylphenol ethoxycarboxylates (APEC) in the aqueous
and particulate phase of wastewater samples. Quantification was achieved by
liquid chromatography-tandem mass spectrometry. The sensitivity of the method is
demonstrated by low detection limits, in the dissolved phase 1.2–9.6 ng l−1 for
alkylphenol, AP1–3EO and APEC and 0.1–4.1 ng l−1 for longer chain alkylphenol
polyethoxylates. The method detection limit for particulate phase samples ranged
from 6 to 60 ng g−1 for AP, AP1–3EO and APEC; with the longer chain APEO being
from 0.5 to 20 ng g−1. Matrix effects were noted in complex matrix rich samples.
There was a distinct change in the distribution of alkylphenol ethoxylates
during biological treatment of the wastewater, with the major biotransformation
products observed being carboxylated derivatives at concentrations of up to 1768
ng l−1. Shorter chain APEO were present in higher proportions in the suspended
solids, due to their higher affinity to particulate matter compared to the lon |
