Abstract (en)
[origin: WO2010094692A1] The invention relates to a method for chemically decontaminating the surface of a metal component, wherein, in a first treatment step, an oxide layer formed on the component by corrosion of the material of said component is removed from the surface of the component by means of a first aqueous treatment solution containing an organic decontamination acid and in a subsequent second treatment step, the surface at least partially free of the oxide layer is treated with an aqueous solution containing an active component for removing particles which adhere to the surface. The active component consists of at least one anionic surfactant from the group consisting of sulphonic acids, phosphonic acids, carboxylic acids and salts of said acids.
