Abstract[English]
A method of recycling a waste ionomer material comprising at least one ionomer and at least one platinum group metal catalyst, the method comprising: (a) mixing the waste ionomer material to homogenize the waste ionomer material; (b) taking a sample of the homogenized waste ionomer material; (c) assaying the sample of homogenized waste ionomer material to characterize ionomer content and platinum group metal content of the waste ionomer material; and (d) recycling the waste ionomer material to separate and recover both the ionomer and the platinum group metal materials on the basis of the ionomer content and the platinum group metal content determined by the assaying.[French]
L'invention concerne un procédé de recyclage d'un matériau ionomère usagé comprenant au moins un ionomère et au moins un catalyseur métallique du groupe du platine, le procédé consiste à : (a) mélanger le matériau ionomère usagé pour homogénéiser le matériau ionomère usagé ; (b) prélever un échantillon du matériau ionomère usagé homogénéisé ; (c) doser l'échantillon de matériau ionomère usagé homogénéisé pour caractériser la teneur en ionomère et la teneur en métal du groupe du platine du matériau ionomère usagé ; et (d) recycler le matériau ionomère usagé pour séparer et récupérer à la fois l'ionomère et les matériaux métalliques du groupe du platine sur la base de la teneur en ionomère et de la teneur en métal du groupe du platine déterminées par le dosage.
