Abstract:
Electrochemically activated glassy carbon electrodes were applied to the preconcentration and electroanalysis of Vitamin B2 (VB2) in multivitamin preparation. Voltammetric peak currents showed linear response for VB2 concentrations in the range between 0.1 to 3.0 M with a large slope of 12.2 AM-1 and a correlation coefficient of 0.996. The reproducibility of the voltammetric measurements was usually less than 7% RSD for five replicate measurements. Common vitamin and metal species did not interfere the determination.
