Sulfate-radical-based advanced oxidation processes (SR-AOPs) have been widely applied in environmental remediation during the past decade, especially in the degradation of refractory organic contaminants. The electrochemical method, which is considered as one of the most efficient ways to generate sulfate radical, has been extensively investigated for the activation of persulfate recently. This work presented a thorough assessment towards the performance of electrochemically activated persulfate for the removal of persistent organic pollutants (POPs) in aqueous systems. The mechanism and superiority of electrochemically activated persulfates were revealed accordingly. Some major factors (e.g., electrode material, pH, current density, and persulfate concentration) influencing the electrochemical activation of persulfates to remove POPs were also discussed. Considering the increasing quantity of publications on this subject, it is significant to broader guidelines such as the efficiency for practical application, quantization of organic by-products, and cost-effectiveness of the electrochemical method to optimize active persulfate in the water treatment processes.

通过过硫酸盐的电化学活化修复水系统中的持久性有机污染物：综述。
在过去的十年中，基于硫酸根的高级氧化工艺（SR-AOPs）已广泛应用于环境修复，尤其是难降解有机污染物的降解。电化学方法被认为是产生硫酸根的最有效方法之一，近年来已被广泛研究用于活化过硫酸盐。这项工作对电化学活化过硫酸盐去除水系统中持久性有机污染物 (POPs) 的性能进行了全面评估。从而揭示了电化学活化过硫酸盐的机理和优越性。一些主要因素（例如，电极材料、pH、电流密度、和过硫酸盐浓度）影响过硫酸盐电化学活化去除持久性有机污染物的问题也进行了讨论。考虑到关于这一主题的出版物数量不断增加，这对更广泛的指导方针具有重要意义，例如实际应用的效率、有机副产物的量化以及电化学方法在水处理过程中优化活性过硫酸盐的成本效益。
