Notes:
A novel method for the photoelectroanalysis of anthracene, as a model compound, is proposed. This technique utilizes a gold electrode in a flowing system of electrolyte, air saturated with oxygen. On irradiation of the electrode with UV-vis light there is a reduction in the level of the oxygen four-electron reductive limiting current due to a reaction of the excited state anthracene and oxygen in acetonitrile/water solution. A linear response over four orders of magnitude (10-2 to 10-1 mol dm-3 was observed between this reduction of current and the concentration of anthracene suggesting the application of this type of technique to the detection of trace levels of aromatic molecules.
