Abstract
This study evaluated the methodology for determining bisphenol A (BPA) in mineral water by using the solid phase extraction (SPE), the derivatization with trifluoroacetic anhydride (TFAA), and the gas chromatography with electron capture detector (GC/ECD) analysis. The analytical curve provided the correlation coefficient (R) of 0.999, and the recovery values from 88 to 106%. The limit of detention was 2.5 and the limit of quantification was 25.0 ng.mL-1. Four mineral water samples from different brands were analyzed by this methodology and among them only one (sample 3) showed detectable result of 0.46 ng.mL-1. This study suggested that BPA could be easily detected and quantified in mineral water samples by employing the proposed methodology, which was selective, accurate and precise.
