Investigation of operational conditions for the removal of methylene blue by Fenton Reaction

Abstract

Fenton reaction has been concerned by many researchersdue to easy operation and effective degradation of bioresistantorganics. This study aims to investigate the effect ofthe operational conditions on the effectiveness of Fenton’sprocess for the decolorization of methylene blue.The influenceof methylene blue, pH, dose of H2O2 , ferrous sulfateconcentration from the wastewater were studied. Experimentshave shown that highly affect by the value of pH, Laboratoryexperiment conducted in the lab proved that pH should bebetween 3 - 4 to give the best results, It also proved that theincreasing of the dose of both hydrogen peroxide and ferroussulfate enhanced the removal efficiency of MB.
