The effect of protic ionic liquid in the reduction of air contaminant gases emitted from electrical discharge machining in the presence of magnetic field.

ABSTRACT: This study investigates the emissions of CO, CO₂, NO, NO₂, SO₂, and H₂S during Electrical Discharge Machining (EDM) using protic ionic liquids (PILs) combined with a magnetic field, a novel approach to enhance environmental performance. Ethanolamine formate (MEA), diethanolamine acetate (DEA), and triethanolamine lactate (TEA) were added at 1 v/v% and 3 v/v% concentrations to kerosene dielectric, with a 300 G magnetic field applied at discharge energies of 30 µJ and 120 µJ. PILs significantly promote oxidation, converting incomplete combustion products (CO, H₂S) into fully oxidized forms (CO₂, SO₂). MEA exhibited the strongest effect, achieving the greatest reductions in CO and H₂S emissions. Higher PIL
