Determination of Pyromellitic Acid in Aqueous Matrices by CE



An analytical method for the capillary electrophoresis determination of pyromellitic acid in aqueous media used as “food simulants” has been developed and is described in this paper. The proposed method determined the pyromellitic acid at ppb levels and is based on a capillary zone electrophoresis separation using coated fused-silica capillary column with a carbonate running buffer and a UV-Vis detector. The method herein developed has been applied to the determination of pyromelitic acid residues leached from plastic bottles. The amount of pyromellitic acid determined in different batch of polyethyleneterephthalate bottles is 2.18%, while the limit of detection is 2.30 ng mL−1 with a relative standard deviation of 4.40%.
