摘要:
基于高盐废水，构建了电化学氯氧化（EO-Cl）系统，以实现阳极新污染物高效去除的同时阴极协同产氢。结果表明，EO-Cl系统因电解过程中会生成活性物质（羟基自由基、活性氯物种、游离氯等）而表现出优异的新污染物去除效能，10 min内对卡马西平的去除率高达98.2%，其中Cl2·-对卡马西平的降解起关键作用，而羟基自由基介导了活性氯物种的生成。在此基础上提出了活性氯物种的生成路径，并研究了工况参数对新污染物降解的影响。对于阴极产氢反应，氯氧化反应成功取代了析氧反应，系统产氢速率达到18.6 μmol/min。在添加新污染物后，EO-Cl系统的法拉第效率提升至94.2%，显著促进了析氢反应。
Abstract:
In this study, an electrochemical chlorine oxidation (EO-Cl) system was constructed to realize the efficient removal of emerging contaminants at the anode and simultaneous H2 production in the high-salt wastewater. The EO-Cl system exhibited excellent performance in removing emerging contaminants due to the active species generated during electrolysis, including hydroxyl radical, reactive chlorine species, and free chlorine. The removal rate of carbamazepine reached 98.2% within 10 min, in which Cl2·- offered the greatest benefit to the degradation of carbamazepine, and hydroxyl radical mediated the generation of reactive chlorine species. Based on these findings, a pathway for the generation of active chlorine species was proposed, and the effects of operational parameters on emerging contaminants degradation were investigated. For the cathode hydrogen evolution reaction, the chlorine oxidation reaction successfully replaced the oxygen evolution reaction, and the hydrogen production rate of the system reached 18.6 μmol/min. With the addition of emerging contaminants, the Faraday efficiency of the EO-Cl system was increased to 94.2%, markedly promoting the hydrogen evolution reaction.
