Method for treatment of oil on a solid or liquid surface to facilitate subsequent removal of the oil from the surface. A fat-soluble metal containing substance comprising an organic anion and a metallic cation is added to the oil. The metal containing substance may be prepared by allowing a metal salt to react with an acidic organic compound in a process in which a suitable oxidation agent ensures that all the metal in the end product is present at its highest stable oxidation state while at least one volatile compound is formed during the preparation. A polymeric material with a high specific surface area may optionally be added or a prepolymer for allowing subsequent formation of such a polymeric material.

L'invention porte sur une méthode de traitement d'une huile sur une surface solide ou liquide afin de faciliter son retrait ultérieur de la surface. Une substance contenant un métal soluble dans une matière grasse comprenant un anion organique et un cation métallique est ajoutée à l'huile. La substance contenant le métal peut être préparée en faisant réagir un sel métallique avec un composé organique acide dans un processus selon lequel un agent d'oxydation approprié permet que tout le métal du produit final soit présent à son état d'oxydation le plus élevé et qu'au moins un composé volatile se forme pendant la préparation. Un matériau polymère à surface spécifique peut être éventuellement ajouté ou un prépolymère pour permettre la formation ultérieure de ce matériau polymère.
