O-phenylenediamine (OPD), a typical representative of aniline compounds found in non-aqueous phase liquids (NAPLs), is extensively released into groundwater and adheres to aquifers through industrial discharges or as breakdown products of pesticides or herbicides [1]. Given its substantial toxicity and suspected carcinogenicity (Lethal Dose, 50% (LD50) = 1070 mg/kg), a reliable, swift, and eco-friendly method for removing OPD from groundwater is urgently needed [2], [3].
