High-Performance Liquid Chromatographic Method for the Determination of Bisphenol A, Nonylphenol and Octylphenol in Sewage

This research is based on high performance liquid chromatographic method for the determination of bisphenol A, nonylphenol and octylphenol in sewage. Sewage samples use dispersive liquid–liquid extraction-pre column derivatization-High performance liquid chromatography method for the determination. Dichloromethane is extracting agent. Acetonitrile and water (V:V = 90:10) are mobile phase. Bisphenol A, nonylphenol and octylphenol detect by Inertsil ODS-P column (5 μm, 250 × 4.6 mm) after the separation of fluorescence. Fluorescence excitation wavelength is 227 nm. The emission wavelength is 313 nm. Sample complete in 6 min within the peak. Linear range is 0.1−10 mg/L. In 0.1, 0.5 and 1 mg/L three concentrations of added level of sewage recovery of samples are respectively 94.7–106.8 %. The method is simple, rapid and economic actual samples. It can be used for sewage.
