To elucidate the interaction mechanisms between iron-manganese minerals and antibiotics/antibiotic resistance genes (ARGs), enhance the understanding of their environmental degradation behaviors, and advance remediation technologies, this study systematically investigates the multifaceted degradation mechanisms of antibiotics by iron-manganese minerals. The mechanisms are explored through the following pathways: synergistic catalysis through surface Brønsted acid sites, Lewis acid sites, and hydroxyl groups promoting antibiotic hydrolysis; semiconductor-mediated photocatalytic degradation via electron-hole pair generation; direct oxidation by redox-active components such as Fe(III)/Mn(IV) coupled with activation of persulfate/hydrogen peroxide to yield reactive species for complete mineralization; concomitant radical-induced damage to ARGs through phosphodiester bond cleavage and base pair destruction, effectively inhibiting their horizontal transfer and evolution. The practical efficacy of iron-manganese minerals has been demonstrated in diverse environmental matrices including soils, aquatic systems, sludge, and livestock manure, with degradation efficiency dynamically regulated by pH, organic matter content, co-existing ions, and moisture conditions. Future research should prioritize establishing integrated databases mapping antibiotic-ARG co-degradation pathways and toxicity profiles, developing in situ dynamic characterization techniques for mineral interface reactions, engineering environment-adaptive mineral- based composite materials.
