A non‐ionic surfactant (Polyoxyethylene 10 lauryl ether, POLE) was used in MAME followed by SPE for cleaning and preconcentration of the samples. The extracts were determined by HPLC‐UV. With the optimum experimental variables established, the analytical parameters of the method were determined with satisfactory results (relative standard desviation values between 3.9 and 9.3% and detection limits between 6 and 38 ng · g−1). The method was validated using the conventional Soxhlet extraction method.||URI:||http://hdl.handle.net/10553/42775||ISSN:||1082-6076||DOI:||10.1080/10826070801893474||Source:||Journal Of Liquid Chromatography & Related Technologies [ISSN 1082-6076], v. 31 (6), p. 865-877|
