Abstract

Methylene Blue (MB) generates colored effluents that are difficult to treat. Solid Scale Waste (SSW) was studied as a catalyst in a Heterogeneous Fenton process for MB removal. The SSW was identified as a non-porous material with 97.5 % iron oxides. For the oxidative process, the exposure to light, amount of catalyst, and H2O2 dose were tested. The best conditions to enhance MB removal were 0.01g of catalyst, 0.035 mL of H2O2, and light; under these conditions, a removal percentage of 97.41 % was achieved. The kinetics results showed a pseudo-first-order reaction and an Activation Energy of 81.92 kJ/mol.
