The effluent produced from the treatment of industrial minerals with oxalic acid harbors significant amounts of dissolved metal cations and residual oxalic acid, presenting environmental toxicity due to low pH and high concentrations of oxalates and metals. With growing environmental regulations, the need for safe effluent disposal is increasingly critical. This study aims to present a novel photochemical treatment method for effectively oxidizing simulated industrial effluents containing high oxalate levels by employing hydrogen peroxide (H2O2) assisted by UV radiation. The dual objectives of this approach are the complete degradation of oxalic acid into harmless components, namely water and carbon dioxide, and the effective recovery and precipitation of metallic species as sludge. A comprehensive examination of the degradation mechanisms of oxalic acid under varying conditions using UV/H2O2, UV/H2O2/Fe2+, and UV/H2O2/Fe3+ systems is conducted. The research experimentally validates the applicability of these methods for the targeted effluents while proposing an economically viable scheme for treatment and metallic recovery. The findings underscore the potential of advanced oxidation processes in achieving environmental sustainability in wastewater management.
