中文摘要：

以2-乙基蒽醌修饰的石墨／聚四氟乙烯电极作为阴极，通过电芬顿反应降解纤维素，考察了盐酸浓度、电解电位和氯化亚铁含量等因素对纤维素降解的影响。结果表明，由1mol／L盐酸和0．4g氯化亚铁组成的100mL溶液中，在电解电势为-1．2V（VS．SEC）下，电化学降解4h，纤维素的解聚率为85．8％。采用苯酚一硫酸法确定了降解产物中可溶性糖的含量，用核磁和质谱对降解液中的提取物进行了表征，分析表明，产物中含有5-羟甲基糠醛。文章把环境友好的电芬顿法引入到纤维素的降解研究中．取得了初步进展，推动了可再生能源纤维素的利用。

英文摘要：

The graphite/PTFE electrodes modified by 2-ethylanthraquinone （EAQ）was chosen as cathode. Through the Electro-Fenton degradation of cellulose,the effect of HCL concentration, electrolytic potential and iron dichloride cotent on cellulose degradation were investigated.The resuits showed that 100 mL solution of 1 mol/L HCL and 0.4 g FeC12 ,which was electrolysed at -1.2 V for 4 h, the depolymerization rate of cellulose could reach 85.8%. The degradation products of the cellulose contained soluble sugar and 5-HMF which was fully characterized by NMR and MS analysis.
