Annotation

Amperometric sensor for eugenol based on glassy carbon electrode (GCE) modified with CeO2 nanoparticles dispersed in surfactant was fabricated. The effect of surfactant nature (sodium dodecylsulfate, cetylpyridinium bromide (CPB) and Brij 35) on eugenol voltammetric behaviour was tested. In comparison to CeO2-H2O/GCE, CeO2-CPB/GCE showed 2.8-fold increased current and 70 mV cathodic shift of potential in the diffusioncontrolled irreversible electrooxidation. The electrodes were characterized with SEM and EIS. CeO2-CPB/GCE showed significantly lower charge transfer resistance (2.6?0.3 kΩ vs. 20?1 kΩ for CeO2-H2O/GCE and 173?9 kΩ for GCE). Under conditions of DPV, the sensor linear dynamic range is 0.075-75.0 mM of eugenol with the limits of detection (LOD) and quantification (LOQ) of 19.1 and 63.8 nM, respectively. The sensor exhibited high sensitivity, selectivity, good reproducibility and fast response and was applied for the real samples analysis (essential oils and clove spices).
