研究了非生物阴极和生物阴极组成的生物电化学体系对氯霉素的还原降解。结果表明，生物阴极组前24 h的CAP还原效率为86.3%，而非生物阴极组前24 h的CAP还原效率仅为62.9%。除阴极电位外，生物阴极组的阴极电流、循环伏安法的电流响应、欧姆电阻、极化电阻等阴极性能指标均优于非生物阴极组。以污泥发酵液为碳源的生物阴极的CAP比还原速率（0.199 h（-1））与葡萄糖（0.215 h（-1））相近，但约为非生物阴极（0.062 h（-1））的3.2倍。这表明生物阴极的引入将改善阴极性能，进而进一步提高CAP还原率。(C)2013爱思唯尔有限公司保留所有权利。
Reductive degradation of choramphenicol (CAP) using Bioelectrochemical system (BES) with both abiotic cathode and biocathode was investigated. It was found that the CAP reduction efficiency during the first 24 h reached 86.3% of the biocathode group, while which was only 62.9% in the case of abiotic cathode. Except for the cathode potential, other indicators of the cathode performance as the cathode current, the current response of the cyclic voltammetry, the ohm resistance, and the polarization resistance of the biocathode group were all better than those of the abiotic group. Moreover, specific CAP reductive rate of the biocathode with sludge fermentation liquid (0.199 h(-1)) as carbon source was close to that of the glucose (0.215 h(-1)), but was about 3.2 times of the abiotic cathode group (0.062 h(-1)). It suggested that the introduction of biocathode would better the cathode performance, and then further increase the CAP reduction. (C) 2013 Elsevier Ltd. All rights reserved.
