Abstract—The main goal of this contribution is the
development of a new heterogeneous Fenton-like oxidation
system based on Prussian Blue supported over a commercially
available granular activated carbon (GAC). The catalysts were
prepared following basically three different approaches: (i)
Prussian Blue (Fe
3[Fe(CN)
6]
2) particles adsorbed onto the GAC
by impregnation, (ii) Prussian Blue nanoparticles (PBNP)
prepared ex-situ and adsorbed onto the GAC; and (iii) PBNP
prepared in-situ onto the GAC. The catalysts were
characterized by SEM, EDS, BET surface area and Fe content.
Their performance in the catalytic wet peroxide oxidation of a
model azo dye, Orange G, was tested in a batch lab-scale stirred
reactor. Activity and stability runs were carried out and
analyzed in terms of dye discoloration, Total Organic Carbon
removal, UV-vis spectra and degree of iron leaching.
Index Terms—Activated carbon, azo dye, heterogeneous
fenton-like oxidation, prussian blue nanoparticles.
