Abstract: | The glassy carbon electrode was modified by copper nanoparticles/carbon nanotubes and nation. The electrochemical characteristics of Bisphenol A on modified electrode were studied. CV was used to study the electrochemical behavior and the content of Bisphenol A in samples that were determined. The results showed that in the PBS buffer solution(pH =7.0) , the concentration of Bisphenol A within 2. 0 × 10-7 -2.0 × 10-5 mol/L presented a good linear relationship with the stripping peak current, and the detection limit was 3.3 × 10-8 mol/L with good effect. |
