Methods for detoxifying the exhaust gases in the core-making sections of the casting industry were studied. The gases generated when making cores from sand-resin mixtures based on oil-free binders and synthetic resins were evaluated. Tests were conducted on activated carbon AR-3, catalysts containing precious and nonprecious metals, and on solutions of sulfuric acid, hydrogen peroxide, and sodium hypochlorate. The absorption, adsorption, and catalytic methods of cleaning the gas discharges from toxic substances were comparatively assessed. Results show that sorption methods were unsuitable while catalytic methods achieved near-total detoxification.
