dc.description.abstractIn this work, sludge from an oily refinery and urban wastewater treatment plant have been used for the synthesis of activated carbons using ZnCl2 and KOH as activating agents. The materials were used as adsorbents and catalysts for the removal of three antibiotics, e.g., sulfamethoxazole (SMX), trimethoprim (TMP) and ciprofloxacin (CPX). The activated carbons have been fully characterized. Thus, the BET surface area of the materials ranged from 183 to 784 m2/g. Qe values of 127.3 mg/g for SMX onto U-ZnCl2; 168.5, and 179.6 mg/g for TMP and CPX, respectively, onto R-KOH were obtained. The best fitting of kinetic data was found by using pseudo-second order (PSO) model, while Freundlich and Liu models successfully fitted the equilibrium adsorption isotherms. SMX, TMP and CPX adsorption mechanisms were governed by pore filling, π-π interactions and H-bonds. R-KOH material was used for wastewater treatment, finding that the adsorption capacity decreased due to a competitive effect. Regarding the Fenton process, the U-ZnCl2 carbon achieved the total SMX degradation after 60 min. In contrast, TMP and CPX showed the highest depletion in only 20 min. The higher performances of the U-ZnCl2 material may be due to a higher C/O ratio and high N and Zn contents. In the experiments with a real aqueous matrix, similar conversions were achieved, although the kinetic constants resulted in slightly lower values. So, it could be stated that adsorption and Fenton oxidation performance were influenced by the different properties of the carbon materials.
