WebFenton processes have been classified and represented as Fenton circle. They also included some recent studies on Fenton processes analyzing different configurations of reactors … WebThe Fenton reagent is the combination of ferrous ion (Fe++) with H 2 O 2 participating in chemical reactions ( Schrank et al., 2005 ). This reagent act as a catalyser which increases the rate of OH° generation. The Fenton’s oxidation process is a pH adjustment, oxidation reaction, neutralization and coagulation for precipitation.
