Determination of Anilines in River Water, Sediment, and Fish Samples by Gas Chromatography–Mass Spectrometry

Traces of aniline and its methyl, methoxyl, and chloro derivatives in river water, sediment, and fish samples were determined by capillary gas chromatography–mass spectrometry after liquid–liquid extraction and steam distillation. Anilines in the concentration range of 0.03–0.10 ng/mL in water could be determined with relative standard deviations of 1.1–22.1%. The detection limits of the anilines in water, sediment, and fish samples were 0.0042–0.031 ng/mL, 1.2–4.0 ng/g, and 0.5–1.7 ng/g, respectively. Their recoveries from river water, sediment, and fish samples (except for 3,4-xylidine, m-anisidine, and p-anisidine) were 101–121%, 71–136%, and 83–117% with percent relative standard deviations of 2.0–11.9%, 6.4–32.5%, and 3.2–9.7%, respectively.
