Abstract
The electrochemical oxidation of a food dye, fast green FCF has been investigated at a glassy carbon electrode using voltammetric techniques. The dependence of current on pH, concentration, scan rate and excipients was investigated to optimize the experimental conditions. According to the linear relation between peak current and the fast green concentration, differential pulse voltammetric method for the quantitative determination in spiked urine was developed. The linear response was obtained in the range of 30 μM to 0.2 mM with a detection limit of 0.8 μM. The proposed method was applied for the detection of fast green in food and urine as a real sample.
