Low-temperature plasma-assisted nitrogen fixation is a promising method for organic-polluted soil/water remediation, that improves N-fertilizer performance and mitigates ammonia emission. Our study explores a novel approach: plasma bubbles-assisted ammonia treatment, and investigates the role played by various reactive substances in the oxidation of ammonia. The specific reaction pathways and the contribution of OH radicals in the ammonia oxidation process in O₂ plasma treatment are determined. Air emerges as the optimal feed gas owing to a positive feedback loop in the reaction between NO₂⁻ and H₂O₂. Air plasma treatment enriches N in the ammonia solution and minimizes ammonia loss during treatment. This study offers new insights into an advanced plasma-assisted ammonia treatment method.
