  • Abstract A LC-MS/MS method for the analysis of alkylphenol polyethoxylates in environmental waters was developed in this study. Preatment procedures including liquid-liquid extraction and solid phase extraction were compared, it’s concluded that solid phase extraction is the more suitable way due to higher recovery and better stability for the analytical results. The recovery of nonylphenol polyethoxylate and octylphenol polyethoxylate were 62.3-110.7 % and 64.9-112.0 %, limit of detection were 17.60-174.9 ng/L and 7.40-53.56 ng/L.
    Enviromental water samples were collected from eight sampling sites along Love River in Kaohsiung City to investigate the contents of alkylphenol polyethoxylates. The highest concentration of total alkylphenol polyethoxylates was observed at Ming-Cheng Bridge which located at the upstream of Love River. For all of the analyzed compounds, the concentration of octylphenol tetraethoxylate (40.46 μg/L) was the highest in all of the sampling sites. It’s also noticed the concentration of octylphenol polyethoxylate (20.11 μg/L) was higher than that of nonylphenol polyehtoxylate (128.04 μg/L).
