Solution(By Examveda Team)

The method for converting combustible gaseous compounds CO₂ and H₂O, halogen HX and S to SO₂, is Adsorption method.
Adsorption is a surface phenomenon and does not penetrate through the surface to the bulk of the adsorbent, while absorption involves the whole volume of the material, although adsorption does often precede absorption. It is the adhesion of atoms, ions, or molecules from a gas, liquid or dissolved solid to a surface.
