The present invention relates to a method of removing mercury from combustion exhaust gases from combustion plants, such as power stations or waste combustion plants. Previous methods for removing mercury from combustion exhaust gases are structurally complex and cost intensive. The object resulting from this problem is solved by a method, in which the mercury-containing combustion exhaust gases are brought into contact with an adsorption agent, whereby the mercury is substantially adsorbed by the adsorption agent during this contact. After the adsorption has occurred the adsorption agent is separated from the combustion exhaust gases and added to an aqueous solution containing an oxidising agent, whereby the adsorbed mercury goes into solution as Hg2+. The Hg2+-containing solution is subsequently separated from the adsorption agent and the Hg2+ is then removed from the solution. This conduct of the method enables the mercury to be removed from the combustion exhaust gases in a simple and economical manner.
