Abstract
- Synthetic dyes are extensively used worldwide although they instigate adverse environmental and health issues at higher concentrations. A reliable and ultrasensitive electrochemical sensor for nanomolar determination of common food colorant sunset yellow FCF is reported in this paper. The electrochemical sensor was integrated with a regularized neural network to enable intelligent sensing of this azo dye. The sensor was fabricated using a ternary nanocomposite based on silver doped spinel Co 3 O 4 nanorods embedded functionalized multi-walled carbon nanotubes (fCNTs). Co-precipitation method was employed for synthesis of porous Co 3 O 4 nanorods and CNTs were functionalized using acid-treatment approach. Electrochemical investigations based on cyclic voltammetry and differential pulse voltammetry techniques revealed stupendous electrocatalytic performance towards sunset yellow detection. A nanomolar detection limit of 0.8 nM and high sensitivity of 8.79 μA μM−1 cm−2 was exhibited by the developed sensor and real sample analysis experiment was conducted in commercial beverages to validate its practical feasibility. [Display omitted] • Prepared AgNPs-Co 3 O 4 /fCNTs ternary nanocomposite based on sonochemical approach. • Ultrasensitive and reliable detection of commonly used synthetic dye sunset yellow FCF. • This is the first work that reports intelligent electrochemical sensing of sunset yellow. • Nanomolar-level detection limit and high sensitivity was achieved for proposed sensor. • Real sample analysis was conducted in Fanta drink and pineapple juice to ensure practical feasibility.
