Abstract
Simple voltammetric method for practical determination of an antioxidant 2-tert-butylphenol (2-TBF) was developed using gold disk working electrode and linear sweep voltammetry. 2-tert-Butylphenol provided one anodic signal at about +1300mV in the environment of ethanolic solution of H2SO4. A non-linear growth of the response with added amount of 2-tert-butylphenol was observed, and low detection (LOD=0.67 mu gcm(-3)) and quantification limit (LOQ=2.22 mu gcm(-3)) were obtained. Applicability was verified by analysis of samples of mineral and synthetic oils.
