Abstract
AbstractRecently a novel chronopotentiometric method has been introduced that was found useful for assessing antioxidant activity. In our experiments, the performance of chemically modified working electrodes made of different pencil materials were tested in the novel method. Redox mediator film of Meldola Blue was formed on electrode surfaces. The stability of the film, the number of molecules structuring it has been studied. In antioxidant measurements, controlled potential oxidation of the mediator was made followed by recording the open cell potential in time. The initial slope of this was used as analytical signal. Results proved applicability of the pencil probes.
