salts (Hg2+). Mercury poisoning treatment techniques include adsorption, oxidation, and reduction mechanism. The catalyst oxidation method is commonly used for gaseous phase mercury removal, while nanoparticles and nanocomposites can be used for mercury remediation of soil, water, and flue gas due to their high adsorption capacity.
