| Abstract: | The UV/Fenton process is an advanced oxidation process, by which phenols in wastewater can be degraded. Here we investigated the effect of the adding amount of FeSO 4 ?H 2O 2 and the initial concentration of phenols in wastewater on the removal efficiency of phenols. When the concentration of H 2O 2 and FeSO 4 added are 20 and 5mmol/L in water sample, respectively, the phenols removing efficiency is up to 99% after reacting for 20min with the initial concentration, 50mmol/L. The utilizing rate of ultraviolet and visible light would be promoted by adding C 2O 2- 4 ions into UV/Fenton system, therefore the phenols removal efficiency can be increased. |
