eng	Determination of Fatty Alcohol Ethoxylates in the Elbe and Chrudimka Rivers	A method for determination of fatty alcohol ethoxylates in water samples employing reversed phase liquid chromatography has been developed. Fatty alcohol ethoxylates were isolated and preconcentrated using solid phase extraction with the octadecyl silica gel-based sorbent and the mixture of methanol:dichlormethane (9:1 (v/v)) as an elution solvent. After extraction step, isolated alcohol ethoxylates were derivatized using phenyl isothiocyanate reagent with addition of triethylamine as a catalyst. The quantitative parameters, limit of detection and quantification were determined. The mean values of limits of detection and quantification were 20.4 ng mL–1 and 67.9 ng mL–1, respectively. The method has been applied for the analysis of water samples from the rivers Labe and Chrudimka. The determined concentrations of alcohol ethoxylates were in the range of 1–8 ug L–1 with the highest concentrations attributed to nonethoxylated alcohols followed by alcohols with low degree of ethoxylation.
