A sensitive oxidation peak is found at 550mV in linear sweep voltammograms at pH7. Based on this finding, trace levels of bisphenol A can be determined over a concentration range that is linear from 10nM to 104nM, the correlation coefficient being 0.9983, and the detection limit (S/N = 3) being 5.0nM. The method was successfully applied to the determination of BPA in food package. Figure A new electrochemical method was developed for the determination of bisphenol A based on carboxylated multi-walled carbon nanotubes modified electrode.
