Abstract

La presente invenzione concerne un procedimento per l'assorbimento di mercurio metallico da gas di scarico in grandi impianti per mezzo di una soluzione acquosa di lavaggio di un agente d'ossidazione, caratterizzato dal fatto che mercurio metallico con l'agente d'ossidazione forma nella soluzione di lavaggio un sistema Redox con un potenziale Redox da 700 mV a 1300 mV, preferibilmente 800 a 1200 mV.The present invention relates to a process for the absorption of metallic mercury from exhaust gas in large plants by means of an aqueous solution of washing of an oxidizing agent, characterized in that metallic mercury with the oxidizing agent forms in the washing solution a Redox system with a Redox potential from 700 mV to 1300 mV, preferably 800 to 1200 mV.
