| abstract |
The present invention relates to an oxidizing aqueous composition, which is useful in particular in the field of disinfection, hygiene and pollution control, on the one hand, and in the field of surface treatment (in particular a metal surface for its pickling. and / or its passivation), on the other hand, said composition, which contains hydrogen peroxide in water, an RCO2 H / RCO3 H mixture (where R is CH3 or CH3 CH2), and a stabilizing agent which is an acid, and, where appropriate, Ag + ions, being characterized in that it contains ions of at least one metal M which are ions of AgII, AgIII, VV, NbV, TaV, MoVI, WVI, CoIII, InIII or TIIII. Advantageously, this composition may be in the form of a gel. The invention also relates to the process for preparing said composition. |
