Application electrochemical sensor based on nanosheets G-C 3 N 4 /CPE by square-wave anodic stripping voltammetric for measure amounts of toxic tartrazine color residual in different drink and foodstuffs

The present work describes a method (SWASV) techniques for measure of tartrazine color a harmful compound present in real samples, and the extremely harmful to humans and animals even at low concentrations using G-C3N4 nanosheets sensor. Here, we report the use of an electrochemical approach for analytical determination of toxic tartrazine that takes 150 s. The calibration curve was linear in range of the (0.02–18.0 µmol L−1). The current response was linearly proportional to the tartrazine concentration with a R2∼ 0.999. We demonstrated a sensitivity a limit of detection of (0.022 µmol L−1). Finally, sensor nanosheets G-C3N4/CPE introduced to measure toxic tartrazine in different drink and foodstuff samples was used and the chemical nanosheets G-C3N4/CPE sensor made it possible as an excellent sensor with reproducibility for determination other samples.
