摘要：

This paper reports an investigation on the degradation of cellulose via electro-Fenton method. The electrodes chosen were graphite/PTFE electrodes modified by 2-ethylanthraquinone (EAQ). The presence of EAQ greatly improved the rate of hydrogen peroxide formation on air-fed graphite/PTFE electrodes, which was determined by a UV spectroscopic method using molybdate as the color agent. Hydrogen peroxide can react with Fe(2+) to form hydroxyl radicals in an acidic medium, which accelerates cellulose degradation by cleaving the glycosidic bonds between glucose units. The degradation products of the cellulose contain soluble sugar and 5-HMF, which were fully characterized by (1)H NMR and (13)C NMR. (C) 2011 Elsevier Ltd. All rights reserved.
