Abstract: A flow injection spectrophotometric system was projected for monitoring hydrogen peroxide during photodegradation of organic contaminants in photo-Fenton processes (Fe 2+/H 2O 2/UV). Sample is injected manually in a carrier stream and then receives by confluence a 0.1 mol L -1 NH 4VO 3 solution in 0.5 mol L -1 H 2SO 4 medium. The product formed shows absorption at 446 nm which is recorded as a peak with height proportional to H 2O 2 concentration. The performance of the proposed system was evaluated by monitoring the consumption of H 2O 2 during the photodegradation of dichloroacetic acid solution by foto-Fenton reaction.
