Abstract

Decoloration methyl violet dye by Fenton reagent was investigated spectrophotometrically. Reagents concentration, pH value, and metal ion were varied. It was shown that substrate oxidation rate depends non-linearly on dye concentration, Fen+, H2O2, and pH value. The composition of the reaction mixture providing maximum oxidation rate and MV conversion is proposed.
