| Abstract | Electrochemical behavior of butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT) was investigated by cyclic (CV), linear sweep (LSV) and differential pulse voltammetry (DPV) in glacial acetic acid solutions in order to develop a new method for determination of these synthetic antioxidants. A glassy carbon electrode (GC) and a carbon fiber disk microelectrode (CF) were used as working electrodes. Voltammograms recorded at these electrodes show well-defined single waves or peaks attributed to the oxidation of BHA and BHT which proceeds with an irreversible exchange of two electrons. A separation of about 0.24 V between the peak potentials recorded using DPV in their binary mixtures was obtained. Wide linearity ranges were achieved: 0.03-594.62, 0.18-921.37 mg L -1 |
