Abstract

The monomer of plastic, bisphenol A (BPA) was found leached from polycarbonate bottle into the drinking water. The method of BPA analysis using Fourier Transform Infrared (FTIR) is not well studied, hence the objectives of the study are to develop the calibration curve for analysis of BPA using FTIR and to determine the method sensitivity. The leaching of BPA was tested for its factors of the duration and temperature by investigating the water sample in contact with the incorporated BPA-PET for 15, 30, 60, 120 mins and temperature at room temperature, 50 oC and 70 oC for 10 mins. The method of extraction used is liquid-liquid extraction (LLE) and the suitable solvent for BPA analysis is dichloromethane (DCM). The calibration curve for analysis of BPA using FTIR was developed and the detection limit of FTIR was 1.0 ppm. The leaching of BPA increased with the duration of time and temperature.
