摘要: 诺氟沙星(NFX)是最常见的抗生素之一。本文研究了介质阻挡放电等离子体对降解水中NFX的影响。利用紫外分光光度计测量了放电过程中产生的活性物质过氧化氢的浓度。研究了放电功率以及加入不同浓度的Fe2+后对NFX降解效率的影响。结果表明，NFX的降解效率随着放电功率的增加而增加。低浓度的Fe2+有利于促进NFX的降解，高浓度的Fe2+会产生抑制作用。本文研究发现Fe2+的浓度为10 mg/L时，NFX的降解效率最高。
Abstract: Norfloxacin is a widely used antibiotic around the world. This study investigated the degradation feasibility of NFX in aqueous solution by gas-liquid dielectric barrier discharge (DBD) plasma. The concentration of reactive species (H2O2) in water was measured with spectrophotometrically. Dif-ferent discharge voltage and catalyt Fe2+ (various concentrations) were applied to degrade the NFX. Fe2+ at low concentration was found to be beneficial to improve the degradation rate of NFX, while restrained at high concentration. 10 mg/L Fe2+/DBD system was the optimized condition in this study to achieve the highest degradation rate.
