|| Alkylphenol polyethoxylates
Solid phase extraction
||In April and June 2012, environmental water samples were collected from fourteen sampling sites in Hengchun peninsula to investigate the contents of alkylphenol polyethoxylates.|
A solid phase extraction combined with LC-MS/MS method for the analysis of alkylphenol polyethoxylates in environmental waters was developed in this study. The mobile phase used methanol gradient elution with deionized water. The recovery of nonylphenol polyethoxylate and octylphenol polyethoxylate were 68~94 % and 65~93 %, limit of detection were 1.89~54.20 ng/L and 0.44~39.31 ng/L, limit of quantitative were 6.29~181 ng/L and 1.48~131 ng/L.
The SsuChung river contents of NPEO and OPEO were 15.64~36.29 μg/L and 3.14~7.37 μg/L. The Paoli river contents of NPEO and OPEO were 16.65~76.41 μg/L and 5.66~18.80 μg/L. The Hou Bay contents of NPEO and OPEO were 34.79~66.72 μg/L and 7.77~19.03 μg/L. The Shihniou river contents of NPEO and OPEO were 26.67 μg/L and 6.68 μg/L. The Wanli Tong, Baisha, Houbi Lake, South Bay, Caesar and Siangjiao Bay contents of NPEO and OPEO were 14.17~48.82 μg/L and 3.88~14.79 μg/L. The dry season concentration contents of alkylphenol polyethoxylates were high than the wet season. The concentration of nonylphenol polyethoxylate was higher than that of octylphenol polyehtoxylate.
