Based on the unique electronic properties and high adsorption capacity of carbon nanotubes, as well as the specific recognition ability of molecularly imprinted polymers, a novel molecularly imprinted carbon nanotubes electrochemical sensor with high sensitivity and selectivity was developed for bisphenol A (BPA) determination in water. The sensor was fabricated by directly thermalpolymerising molecularly imprinted film on a multi-wall carbon nanotubes (MWNTs) modified glassy carbon electrode (GCE). The linear sweep voltammogram of BPA on this sensor exhibited a well defined anodic peak. Under optimum conditions, the oxidation peak currents were linear to the concentration of BPA in the range of 0.1 mg/L-10.0 mg/L with a correlation coefficient of 0.9987 and a detection limit of 24.2 μg/L (S/N = 3). The proposed electrode exhibited good sensitivity and selectivity, and provided operation and store stability for the determination of BPA. The experiment results indicated a good potential application of the modified sensor in the detection of BPA.

Abstract A method has been developed for determination of bisphenol A diglycidyl ether (BADGE) in 3 aqueous-based food simulants: water, 15% (v/v) ethanol, and 3% (w/v) acetic acid. BADGE is extracted with C18 cartridges and the extract Is concentrated under a stream of nitrogen. BADGE is quantltated by reversed-phase liquid chromatography with fluorescence detection. Relative precision at 200 μg/L was 3.4%, the detection limit of the method was 0.1 μg/L, and recoveries of spiking concentrations from 1 to 8 μg/L were nearly 100%. Relative standard deviations for the method ranged from 3.5 to 5.9%, depending on the identity of the spiked aqueousbased food simulant.
