Abstract

A highly sensitive and simple method for the determination of heptaoxyethylene dodecylether (HOE) by fluorescent derivatized high performance liquid chromatography in conjunction with preconcentration by an α-hydroxyethylated styrene-divinylbenzene resin column was developed. This method showed a recovery rate as high as 92% with a standard deviation below 10%. The lower limit of determination in river water was 1μg/1.
