【 摘 要 】

The electrochemical sensors for carmoisine detection were explored and applied in the field of food safety because of the striking merits of fast detection speed, high sensitivity and easy operation. Herein, we de­veloped a high-performance electrochemical carmoisine sensor based on g-C3N4 and ionic liquids (ILs), prepared by a one-pot hydrothermal synthesis method. Most importantly, the sensing per­formances of electrochemical carmoisine sensors based on g-C3N4 (graphitic carbon nitride)/IL (1-butyl-3-methylimidazolium hexafluorophosphate) are better than the bare carbon paste electrode (CPE) sensors. The detection limit of this sensor (g-C3N4/ILs/CPE) de­ter­mined via differential pulse voltammetry was 0.1 µM over a wide linear range of 0.4–125.0 µM.
