Organic acid is prevalent in underground environments and, against the backdrop of biogeochemical cycles on Earth, holds significant importance degradation contaminants by redox-active minerals. While earlier studies role organic generation reactive oxygen species (ROS) primarily concentrated electron shuttle or ligand effects, this study delves into combined impacts decomposition and Mackinawite (FeS) oxidation contaminant transformation under dark aerobic conditions. Using bisphenol A (BPA) as a model, our findings showed that oxalic (OA) notably outperforms other acids enhancing BPA removal, attaining rate constant 0.69 h-1. Mass spectrometry characterizations, coupled with anaerobic treatments, advocate for molecule-O2 activation principal mechanism behind pollutant transformation. Comprehensive results unveiled carbon center radicals, initiated hydroxyl radical (•OH) attack, serve primary agents oxidation, accounting at least 93.6% total •OH generation. This dynamic, driven concurrent formation carbon-centered ensures steady supply electrons ROS The obtained information highlights OA natural attenuation pollutants offers innovative strategies FeS acid-coupled decontamination.
