Abstract
A method recovers noble metals from noble metal-containing compositions and includes steps of (i) providing a noble metal-containing composition containing an adsorption agent that is based on an inorganic material and is functionalized by organic groups and has at least one noble metal adsorbed to it, and (ii) ashing of the noble metal-containing composition provided in step (i) in order to adjust a residual carbon content of at most 10% by weight, relative to the total weight of the noble metal-containing composition after ashing, to obtain an ashed composition.
