Assay of antioxidants by the quenching of the anthracene-sensitized electrochemiluminescence.
The kinetic and spectral characteristics (chemiluminescence and fluorescence spectra) of ultraweak luminescence accompanying the electrolysis of a sodium citrate-methanol-dissolved O2 solution and its application for the determination of antioxidants were examined. The energy transfer-assisted luminescence sensitized by anthracene provides a fast and sensitive assay for the determination of the concentration and kinetic parameters of antioxidants and free radical scavengers.
