The degradation of mono-chloroacetic acid (MCAA) by microwave-assisted photocatalysis has been examined by a new method. A novel electrodeless discharge lamp (EDL) was employed as UV light source generated by microwave irradiation. Titanium(IV) oxide film was used as the photocatalyst due to its superior characteristics. Several factors influencing the degradation of MCAA, such as number of coating cycles, light intensity, initial pH value, gas bubbling, and H(2)O(2) dosage have been studied in detail. Mono-chloroacetic acid was efficiently decomposed to HCI, CO(2), and H(2)O by the UV irradiated titanium dioxide thin film in a microwave field. The decomposition was enhanced in an alkaline solution and in the presence of H(2)O(2), and significantly enhanced by increasing the intensity of UV light. (c) 2008 Elsevier B.V. All rights reserved.
