Sažetak
In this study, we report the electrochemical detection of sunset yellow (SY) at the surface of a carbon paste electrode (CPE) modified with CuCo2O4 nanorods (NRs) and an ionic liquid (IL). The electrochemical behavior of sunset yellow at the modified electrode was investigated using linear sweep voltammetry, differential pulse voltammetry and chronoamperometry techniques. The CuCo2O4 NRs/IL/CPE sensor exhibited good performance and favorable electrochemical response for the electrochemical reaction of SY in a 0.1 M phosphate buffer solution at pH 7.0. The results showed a linear electrochemical response to SY within the concentration range of 0.2 to 160.0 μM, with a detection limit of 0.06 μM. In addition, The CuCo2O4 NRs/IL/CPE sensor demonstrated good ability for SY determination in real samples.
