|Title:||Flow injection spectrophotometric system for hydrogen peroxide monitoring in photo-Fenton degradation processes.|
|Abstract:||A flow injection spectrophotometric system was projected for monitoring hydrogen peroxide during photodegradation of organic contaminants in photo-Fenton processes (Fe2+/H2O2/UV). Sample is injected manually in a carrier stream and then receives by confluence a 0.1 mel L-1 NH4VO3 solution in 0.5 mel L-1 H2SO4 medium. The produce formed shows absorption at 446 nm which is recorded as a peak with height proportional to H2O2 concentration. The performance of the proposed system was evaluated by monitoring the consumption of H2O2 during the photodegradation of dichloroacetic acid solution by foto-Fenton reaction.|
