Abstract
A method of remediating methyl amine and/or methyl amine derivative odors in aqueous systems by contacting the methyl amine or methyl amine derivative with a compound having amide or imide functionality, such as a hydantoin composition, in the presence of hydrogen peroxide. The amide/imide composition is preferably a non-halogenated, singe-ring hydantoin that binds methyl amines to the amide or imide functional group of the hydantoin.
