Print)||Abstract:||A simple and rapid HPLC method with spectrophotometric detection to determine phenolic compounds in water, including the 11 priority phenolic pollutants, is described. As they are present in low concentrations, an extraction and preconcentration step is necessary prior to their determination. A methodology based on the cloud point phenomenon is applied using the non-ionic surfactant oligoethylene glycol monoalkyl ether (Genapol X-080) as extractant. The optimum conditions for the extraction and preconcentration of phenolic derivatives have been established and detection limits lower than 10 µg L−1 were obtained for all studied compounds. The method has been applied to their determination in sea water and depurated waste water samples.||URI:||http://hdl.handle.net/10553/47170||ISSN:||0003-2654||DOI:||10.1039/b202092k||Source:||Analyst [ISSN 0003-2654], v. 127, p. 1031-1037|
