摘要(Abstract)：

针对水体中存在的氧氟沙星等新兴污染物难以去除的问题，采用高锰酸钾直接氧化法在泡沫镍Ni表面原位生长氢氧化镍Ni(OH)₂花状纳米片阵列，制备具有三维阵列结构的Ni/Ni(OH)₂电极，对所制备电极的微观结构和元素组成进行分析和表征；以Ni/Ni(OH)₂电极为阴极，碳纤维毡为阳极，搭建穿透式电活化过一硫酸盐反应器，并考察该反应器去除氧氟沙星的性能及其影响因素。结果表明：该反应器运行参数对氧氟沙星的去除有显著影响，当过一硫酸盐浓度为1 mmol/L、施加电压为2.5 V、水力停留时间为3.86 min、反应器中电解液pH值为7时，氧氟沙星的去除率达81.9%;通过自由基猝灭实验和原位电子顺磁共振波谱分析证实，反应系统内羟基自由基·OH和单线态氧¹O₂是主要的活性物种，在电活化过一硫酸盐去除氧氟沙星过程中发挥关键作用。
