A rapid method for the HPLC determination of pyromellitic acid in aqueous media used as “food simulants” has been developed and is described in this paper. The proposed method can determine pyromellitic acid at ppb trace levels and is based on an ionic exchange separation mechanism. The method herein developed has been applied to the determination of pyromellitic acid residues leached from plastic bottles.
