Degradation of 4-chlorophenol in aqueous solution photoinduced by Fe(III)-citrate complex
Original language description
The 4-chlorophenol (4-CP) degradation photoinduced by Fe(III)-citrate complex was investigated upon irradiation at 365 nm at different pHs (2.0, 3.0, 4.0 and 6.0). The best efficiency for 4-CP degradation in the presence of Fe(III)-citrate was at pH 3.0with a value of quantum yield equal to 0.026. This effect is mainly attributed to speciation of Fe(III)-citrate complex which is very sensitive to the pH. Quantum yields of 4-CP degradation, Fe(III)-citrate disappearance and Fe(II) formation were carriedout at wavelength 365 nm at different pHs (3.0 and 6.0). The effect of the pH is less pronounced for the quantum yields of 4-CP than for Fe(III)-citrate complex and Fe(II) quantum yields which are species involved in the initial photochemical process. The effect of oxygen, isopropanol and Fe(III)-citrate concentrations on the quantum yields of 4-CP degradation and also on kinetics of 4-CP disappearance was also studied. Indeed, 4-CP requires the presence of oxygen to be degraded. The di
