摘要

The present invention relates to a method of selective extraction of a platinoid, from a ceramic support containing a metal, comprising the following successive steps: a) the support is brought into contact, with an extraction medium consisting of a pressurized dense fluid containing an organic ligand that is selective for the metal and that is capable of forming a complex with the metal in the 0 state; whereby a ceramic support depleted in the metal, or even free of the metal, and, a medium consisting of the fluid containing the complex of the organic ligand with the metal in the 0 state are obtained; b) the fluid is brought back to atmospheric pressure and to ambient temperature, whereby the complex separates from the fluid; c) the ceramic support depleted in the metal, or even free of the metal, and the complex, are recovered.
