Abstract

This study introduced electrochemical activation of 2-(4-((3-(trimethoxysilyl) propylthio)methyl)1-H1,2,3-triazol-1-yl) aceticacid-Fe3O4 nanoparticle (Fe3O4 NPs derivative)-modified screen-printed electrode (Fe3O4 NPs/SPE) for electroanalytical determination of bisphenol A. In comparison to the bare electrode, Fe3O4 nanoparticles-modified electrode largely increased the oxidation peak current of bisphenol A and decreased oxidation overpotential. This implies that the modified electrode can significantly promote determination sensitivity of bisphenol A. The bisphenol A oxidation peak current gained by DPV enhanced linearly with its concentration at the range between 0.03 and 700.0 mu M, while Pearson correlation coefficient was equal to 0.9998 and limit of detection was less than 0.01 mu M.
