Abstract
A method and system for determining organic matter in an aqueous solution including an oxidizing agent are disclosed. The method includes contacting the solution with a semiconductor which is capable of photocatalytically oxidizing the organic matter, illuminating the semiconductor with light of a wavelength or having a spectrum whereby the semiconductor photocatalytically oxidizes the organic matter in the solution to form a photocatalytic by-product(s), and detecting the by-product(s). The system includes a photocatalytic reactor (104) having a semiconductor, which is capable of photocatalytically-oxidizing the organic matter to form a photocatalytic by-product(s), disposed therein so as to contact the solution when disposed in the reactor, an illumination source (103) disposed to illuminate the semiconductor in the reactor wherein the source is capable of emitting light of a wavelength or having a spectrum whereby upon illumination of the semiconductor in contact with the solution the semiconductor photocatalytically-oxidizes the organic matter in the solution, and a device for detecting the by-product(s) (108, 109) operatively associated with or operatively coupled to the reactor.
