摘      要：A sensitive electrochemical sensor for determining bisphenol A（BPA） was designed. The sensor was aglassy carbon electrode modified with the surfactant cetyltrimethylammonium bromide and the ionic liquid1-decyl-3-methylimidazolium tetrafluoroborate. The ability of the new sensor to measure BPA was investigated incyclic voltanmletry experiments. Under optimized conditions, the sensor gave a linear response range for BPA of2.19×10^-7 -3.28× 10^-5 mol/L and a detection limit of 7.31×10^8 mol/L（S/N=3） BPA could be determined with a lowerdetection limit, a wider linear range, and more sensitivity using the sensor than using other electrochemical sensors orhigh performance liquid chromatography with UV detection. The new sensor was used to determine BPA in tap waterwith recoveries of 97.5%--98.7% and a relative standard deviation 〈2.9%. The results show that the sensor can beused to determine trace BPA concentrations in tap water.
