dc.description.abstract | BACKGROUND: The degradation and mineralisation of the antibiotic amoxicillin by photo-Fenton reactions, mediated by artificial UVA or solar irradiation, were investigated. Experiments were conducted with 30 mg L−1 amoxicillin solutions prepared with deionised or surface water at Fe2+ and H2O2 concentrations in the range 0.0179–0.0895 and 1–10 mmol L−1, respectively. Black-light irradiation at 365 nm was provided by a 13 W m−2 lamp, while samples were exposed to sunlight at 20 W m−2 for solar experiments. RESULTS: In all cases, quantitative amoxicillin degradation occurred within 5 min and this was accompanied by lower mineralisation rates. Mineralisation followed first-order kinetics with respect to organic carbon content and it was not affected by the water matrix with either type of illumination. Solar-induced reactions were only marginally faster than artificial irradiation. Increasing the H2O2 to Fe2+ concentration ratio increases the extent of mineralisation up to a point beyond which degradation is impeded due to radical scavenging associated with the high concentrations of the Fenton reagents. CONCLUSION: Amoxicillin is readily degradable by homogeneous photocatalysis, being converted to more stable intermediates as indicated by lower mineralisation rates. The process can be driven by solar irradiation, thus providing a sustainable treatment technology. Copyright © 2009 Society of Chemical Industry | en |
