Abstract

Se proveen métodos para la descontaminación de mercurio que incluyen: poner en contacto mercurio elemental con una sal que tiene un potencial de reducción estándar suficiente para oxidar el mercurio elemental a una sal acuosa de mercurio. En otros aspectos, se proveen métodos para la descontaminación de mercurio que incluyen: poner en contacto la superficie de metal con una solución que comprende una sal de metal que tiene un potencial de reducción estándar (E0) mayor de 0.84, oxidando mediante esto el contaminante de mercurio a una sal soluble de mercurio.
