Determination of bisphenol A in drinking water and river water by HPLC

A simple and low cost mesurement method for determination of bisphenol A (BPA) in drinking water and river water by high-performance liquid chromatography (HPLC) with an ultraviolet detecter (UV) has been studied. As a result, good linearity of the calibration curve was obtained in the concentration range from 0.01 mg/l to 1 mg/l. The detection limit, based on S/N = 3, was 0.0065 mug/ml for BPA. Acetone was recommended for the elution of BPA from the solid phases. The recoveries for BPA from river water spiked at a mesurement concentration of 0.1 mg/l was 55.3-78.7%, and the relative standard deviations was 5.2-7.1% by an activated carbon column method. This measurement method could be successfully applied to the determination of BPA in drinking water and river water.
