Abstract:

A rapid, simple, and repeatable method was established to determine bis(2-ethylhexyl) phthalate (DEHP) in
juice by gas chromatography-mass spectrometry (GC-MS). The results showed that its linear range was 1.0–50.0 mg/L (R2 =
0.9978) and the detection limit for DEHP was 0.4 mg/L. Average recovery rates ranged between 87.84% and 105.23% with
relative standard deviation of less than 7%. Therefore, the GC-MS method is suitable for quantifying DEHP in juice and
providing a useful guideline to trace the source of DEHP in juice.

Key words: diethylhexyl phthalate, juice, gas chromatography-mass spectrometry, source tracing
