At normal laboratory temperature and atmospheric pressure, experiment on waste water containing metanil yellow by photo-Fenton process were conducted to examine the effect of operating variables like the concentration of ferric ion, concentration of metanil yellow, pH, hydrogen peroxide and light intensity on the reaction rate. Metanil yellow was completely oxidized and degraded into CO2 and H2O in this experiment. A mechanism for photochemical bleaching of metanil yellow by photo-Fenton’s reaction has been processed.
