Popis: Dispersive liquid–liquid microextraction based on solid formation without a disperser combined with high-performance liquid chromatography has been developed for the determination of 4-tert-butylphenol, 4-n-nonylphenol, and 4-tert-octylphenol. This method is rapid, easy, and uses only 10 µL of a low toxicity organic solvent (1-hexadecanethiol) for the extraction solvent and no disperser solvent. The extraction time and centrifugation time require less than 10 min. The linear range was 1–500 ng mL−1 for 4-tert-butylphenol, 2–1000 ng mL−1 for 4-tert-octylphenol, and 5–500 ng mL−1 for 4-n-nonylphenol with r2 ≥ 0.9986. The detection limits were between 0.2 and 1.5 ng mL−1. The recoveries of lake and river water samples were in the range of 79% to 108%, and the relative standard deviations were 5% to 10%.
