Abstract

L'invention concerne l'utilisation d'acides carboxyliques ou de leurs sels comme constituants anticorrosion essentiels dans des agents de traitement de surfaces métalliques pour préparer ces agents provenant d'un milieu aqueux en fonction de leur utilisation particulière, pour récupérer les acides carboxyliques et éventuellement les recycler dans un agent correspondant.
