Abstract
The potential of leaching Bisphenol-A (BPA) from plastic baby feeding bottles, aluminum cans, and thermal printed receipts was investigated under the aquatic condition at high temperatures. BPA is often used to manufacture cross-linked epoxy resin to coat food cans to prevent direct contact with metals and plastic materials. BPA leached from consumer product was analyzed using UV-Visible Spectrophotometer based on the inhibitory effect of BPA on acridine orange oxidation, as a function of change in temperature and time of contact of water with the samples. The proposed method of BPA estimation method was found to be significant and useful for aquatic conditions without any extraction and/or derivatization. The detection limit of BPA under the current experimental setup was 0.1 ng/ml. The results of BPA leached from baby feeding PET bottles, aluminum 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.
