Abstract

In this study, heterogeneous Fenton oxidation processes is applied, with the usage of nZVI as a catalyst. Greener than the conventional Fenton process, it combines the advantages of nZVI reduction and Fenton oxidation. According to the central composite design and the analysis of variance, the model presents medium R2 value of 73.02% for the Magenta removal. At the 60 min of contact time, dye removal efficiency raised more than 40% and 70% with the increase of hydrogen peroxide concentration and pH decrease, respectively. The experimental results indicate that the oxidation process leads to the reduction in dye concentration up to 97%, confirming the application possibility of Fenton-like oxidation process for the dye removal from the aqueous solution.
