Electrochemical activation of persulfate (EA-PS) is gradually attracting attention as an emerging method for wastewater treatment. In this study, a novelty flow-through EA-PS system was first attempted for pollutants degradation using boron and cobalt co-doping carbon felt (B, Co-CF) as the cathode. SEM images, XPS and XRD spectra of B, Co-CF were investigated. The optimal doping ration between B and Co was 1:2. Increasing current density, PS concentration and flow rate, decreasing initial pH accelerated the removal of AO7. The mechanism involved in EA-PS were the comprehensive effect of DET, OH and SO. B, Co-CF cathode for flow-through system was stable with five cycles efficient AO7 decay performance. EA-PS in flow-through system was an efficient method with low cost and efficient pollutants degradation. This work provides a feasible strategy for synergistically enhancing PS activation and promoting the degradation of organic pollutants.
电化学激活过硫酸盐（EA-PS）作为一种新兴的废水处理方法逐渐引起了人们的关注。在本研究中，首次尝试使用硼和钴共掺杂碳纤维毡（B，Co-CF）作为阴极的新型流通式 EA-PS 系统来降解污染物。对 B，Co-CF 的 SEM 图像、XPS 和 XRD 光谱进行了研究。B 和 Co 的最佳掺杂比为 1:2。增加电流密度、PS 浓度和流速、降低初始 pH 值均加速了 AO7 的去除。EA-PS 的作用机制涉及 DET、OH 和 SO 的综合效应。用于流通系统的 B，Co-CF 阴极具有稳定的性能，可在五个循环中有效降解 AO7。在流通系统中，EA-PS 是一种高效、低成本且能有效降解污染物的方法。这项工作为协同增强 PS 活化和促进有机污染物降解提供了一种可行的策略。
