Application of Fenton Processes for Degradation of Aniline
Application of Fenton Processes for Degradation of Aniline

The ,Fenton, s ,reagent, is generally occurred in acidic medium between pH 2 -4 (Rodriguez et al., 2003). The advantage of ,Fenton, process is the complete destruction of contaminants to harmless compounds, for instance, carbon dioxide and water (Neyen E. et al., 2003). However, its application has been limited due to the generation of the

1/5/2017, · The Fenton’s reagent was discovered by Fenton in 1894, (Fenton, 1894). Fenton’s reagent is a mixture of H 2 O 2 and ferrous iron, which generates hydroxyl radicals. The ferrous iron (Fe ++) initiates and catalyzes the, decomposition of H 2 O 2,, resulting in the generation of hydroxyl radicals.
