[Investigation of the Performance of Organic Contaminant Degradation by Fe/PDS Under Environmentally Relevant pH Conditions].

Peroxydisulfate (PDS) activation by Fe has proven to be a promising method to abate emerging organic contaminants by generating reactive oxidation species. Nevertheless, this process may only achieve good decontamination performance under acidic conditions, which has markedly limited its application in real practice. To address this issue, we comprehensively investigated the performance of the Fe/PDS process toward some probe contaminants at different pH levels and explored the potential change in reactive oxidative species and the influence of oxygen.
