Agent and a method for removing ethidium bromide in a waste solution

Ethidium bromide is a carcinogen. After carrying out relevant DNA or RNA experiments, there is generally produced a waste solution or a pollutant containing ethidium bromide and thus in a laboratory such a waste solution and pollutant must be particularly treated in a way identical to the treatment of poisonous materials.
