Photo-Fenton processes are one of the ecologically viable techniques for degradation of textile dyes
and industrial wastewater treatment. Relatively simple approach, use of simple chemicals for the
degradation, cyclic nature and high reaction yields make this process a green chemical pathway in
reducing pollution caused by dyes and other organic compounds. In the present study, the
photochemical degradation of dye methyl green by photo-Fenton reaction in presence of catechol
as an additive has been investigated. The kinetics of the reaction has been followed
spectrophotometrically. The effect of variation of various parameters such as pH, concentration of
Fe3+ ion, dye and additive; amount of H2O2 and light intensity on the rate of photo degradation has
also been analysed.
