Objective:In order to detect bisphenol A(BPA)rapidly,a molecular imprinted electrochemical sensor modified by nano-materials was constructed.Methods:the gold electrode was modified with nano-materials,and the molecular imprinting sensor for bisphenol A and O-Phenylenediamine was constructed by electrochemical method.The performance of the molecularly imprinted sensor was analyzed by Cyclic voltammetry,the preparation conditions were optimized,and the sensitivity of the sensor was verified and tested.Results:under the optimal experimental conditions,the relationship between the negative logarithm and the peak current difference was linear in the range of 1.0×10^(-10) mol/L~1.0×10^(-3) mol/L.And the sensor has good stability.Conclusion:the bisphenol A molecularly imprinted sensor with practical application value has lower cost,better anti-jamming performance and higher sensitivity.
