| Abstract: | The key to enhance the efficiency of Fenton's reagent in wastewater treatment is to enhance the productivity and utilization ratio of hydroxyl radicals in the system.In this paper,the apparent productivity of hydroxyl radicals in Fenton's reagent system was determined by the method of indirect determination.The leading factors influencing the apparent productivity of hydroxyl radicals in the system such as the concentration of catalyst ferrous iron(Fe 2 ,the amounts of H 2O 2,pH,reaction time and reaction temperature were tested in detail.The useful parameters for Fentionis reagent treating wastewater were offered. |
