abstract = {A series of biochars and activated carbons (ACs) was prepared combining carbonization
and physical or chemical activation of cheap and abundant residues of the olive oil industry.
These materials were used as Fe-support to develop low-cost catalysts for the heterogeneous
Fenton-like oxidation of simulated olive mill wastewater (OMW), the highly pollutant effluent
generated by this agroindustry. Commercial ACs were also used as reference. All catalysts prepared
were extensively characterized and results related with their performances in the catalytic wet
peroxide oxidation (CWPO). Results showed a linear relationship of the textural properties of the
catalysts with the adsorptive and catalytic performance, as well as the preferential adsorption and
degradation of some phenolic compounds (caffeic and gallic acids) by specific interactions with the
catalysts’ surface. Despite the best performance of catalysts developed using commercial supports,
those prepared from agro-industrial residues present some advantages, including a smaller catalyst
deactivation by iron leaching. CWPO results show that catalysts from physically activated olive
stones are the most promising materials, reaching total organic carbon and toxicity reductions of
35% and 60%, respectively, as well an efficient use of H2O2, comparable with those obtained using
commercial supports. This approach showed that the optimized treatment of this type of residues
will allow their integration in the circular economic process of the olive oil production.},
