    • A method for treating a solid substrate comprising a support comprising, preferably consisting of, at least one oxide chosen from the oxides of a first metal chosen from the rare earths, the mixed oxides of a first metal chosen from the rare earths and at least one second metal different from the first metal, and the mixtures of an oxide of a first metal chosen from the rare earths and at least one oxide of at least one second metal different from the first metal, said support comprising at least one surface on which there are deposited particles consisting of at least one noble metal, in order to separate the first metal, the optional second metal, and the noble metal which constitutes the particles, said method comprising a step of selectively dissolving the support, during which the substrate is brought into contact with a dissolving solution comprising at least one mineral acid and at least one reducing agent for reducing the rare earth or rare earths of the support chosen from natural antioxidant molecules such as ascorbic acid, catechol, gallic acid and the mixtures of same, thereby obtaining a solution containing the first metal and the possible second metal in the dissolved state, in which there are suspended the particles consisting of the noble metal.
