摘要: In this project, we performed an electrochemical investigation using a reduced graphene (rG) decorated CdO nanocomposite/1-methyl-3-octylimidazolium tetrafluoroborate ionic liquid (MOITF) carbon paste electrode (rG-CdO/MOITF/CPE) for determination of ferulic acid in food samples. preparation rG-CdO/MOITF/CPE, 6% w/w rG-CdO nanocomposite and 20% v/v room temperature were used to modify the bare CPE. SEM (Scanning Electron Microscopy) XRD (X-Ray Diffraction) methods applied characterize structure synthesized nanocomposite. At all stages research, phosphate buffer solution (PBS) with pH 5.0, as optimized condition, was used. The electron transfer coefficient (α) obtained ⁓0.68 by recorded data from cyclic voltammogram rG-CdO/MOITF/CPE presence acid. addition, chronoamperometric technique, diffusion (D) at calculated 5.4 × 10−5 cm2/s. Using square wave voltammetry method, linear dynamic range (LDR) be 0.02 400 μM, limitation detection (LOD) 8.0 nM. Eventually, utilized determine amount samples, statistical calculations confirmed sensitivity, selectivity, precision which is electroanalytical tool.
