Abstract

We report here the degradation of AY-17 dye using Fenton-like process (H2O2/Fe3+). The maximum degradation (83%) of AY17 dye is achieved at pH 3 in 60 min, with optimum concentrations of AY 17 (0.06 mM), H2O2 (0.9 mM), and Fe2+ (0.06 mM). The scavenging effects of HCO3, CO32−, Cl and SO42− on dye degradation are also examined. The activation energy (Ea), activation enthalpy (rH*), and activation entropy (rS*) are calculated for the dye degradation using pseudo-first-order kinetics at various temperature.
