Seven catalysts have been prepared impregnating a commercially available granular activated carbon (GAC) by sequential addition of aqueous solutions of (K3[Fe(CN)6]) and FeSO4 to produce Prussian Blue (Fe3[Fe(CN)6]2) particles adsorbed onto the support. Alternatively, Prussian Blue nanoparticles (PBNP) have been prepared ex-situ and adsorbed onto the GAC. Performances of the prepared catalyst for Fenton oxidation are tested in a batch stirred reactor and analyzed in terms of dye decolorization, Total Organic Carbon (TOC) removal and degree of iron leaching.
