摘要

In this paper for determination of folic acid in food and tablet samples, some highly conductive MgOnanoparticles (MgO NPs) are used as amplifier for modification of the carbon paste electrode (CPE) asa sensitive tool. The MgO NPs are synthesized by a simple chemical precipitation method and arecharacterized with the XRD method. The oxidation of folic acid appeared at potential ~782 mV withcurrent ~78.8 μA at surface of the CPE/MgO-NPs to better show the experimental results compare tothe CPE with potential ~810 mV and current ~42.2 μA. At pH=9.0, the oxidation of folic acid is detectedat dynamic range 0.09–1000 μM with a detection limit of 0.04 μM (3δ). The CPE/MgO-NPs showedhigh performance capability for analysis of folic acid in food and tablet samples.
