Description
  • The voltammetric determination of synthetic antioxidant 2,6-di-tert-butyl-4-methylphenole (BHT) was studied using linear-sweep voltammetry (LSV) and cyclic voltammetry (CV) with a gold electrode and performed in isopropanol media containing either 0.1 mol/L H2SO4 or 0.1 mol/L LiClO4 as supporting electrolyte. The results obtained have revealed that the most reliable detection was acquired in acidic media (isopropanol-H2SO4) whereas the use of isopropanol LiClO4 solution exhibited poorer reproducibility due to possible passivation of the electrode. Real samples of biodiesel mixture were analyzed without any special sample treatment or separation and results were compared with those obtained by FTIR-spectroscopy.
