A method was developed for the analysis of acetaldehyde (AA) residue in polyethylene terephthalate (PET) bottles using an Agilent 7820 GC with flame ionization detection (FID). This method achieved a low detection limit with a linear range of 0.5–5.0 µg and an R2 of 0.9993. AA residue in the range of 0.03 µg/g was identified in pure water bottle samples by this method.
