BPA in Baby Feeding PET Bottle, Aluminium Can and Thermal Printed Paper: Application of Acridine Orange Oxidation Inhibition Method to Estimate BPA

Abstract The leaching of Bisphenol-A (BPA) from plastic baby feeding bottles, aluminium cans and thermal printed receipts was investigated under aquatic condition at high temperature. Leached BPA was analysed using UV-Visible Spectrophotometer based on inhibitory effect of BPA on acridine orange oxidation, as a function of change in temperature and time of contact of water with the samples. Proposed method of BPA estimation method does not require any extraction and/or derivatization. The detection limit of BPA under current experimental setup was 0.1 ng/ml. The results of BPA leached from baby feeding PET bottles, aluminium can with epoxy resin lining and thermal paper were 87 ± 10 ng/bottles, 68 ± 5 ng/bottle and 110 ± 15 ng/receipt under the current experimental conditions.
