Abstract[English]
A method of quantifying a content of an insoluble metal compound in an aqueous suspension comprising an insoluble metal compound and a metal ion-exchanged molecular sieve is disclosed, The method comprises: treating the aqueous suspension of the insoluble metal compound and the metal ion-exchanged molecular sieve with a selective solubilising agent for the insoluble metal compound, thus producing a treated mixture comprising a metal solution comprising a dissolved metal from the insoluble metal compound and undissolved metal ion-exchanged molecular sieve; and quantifying a dissolved metal content of the treated mixture using a suitable analytical technique.[French]
L'invention concerne un procédé de quantification d'une teneur d'un composé métallique insoluble dans une suspension aqueuse comprenant un composé métallique insoluble et un tamis moléculaire à échange d'ions métalliques, le procédé comprenant : le traitement de la suspension aqueuse du composé métallique insoluble et du tamis moléculaire à échange d'ions métalliques avec un agent de solubilisation sélectif pour le composé métallique insoluble, produisant ainsi un mélange traité comprenant une solution métallique comprenant un métal dissous à partir du composé métallique insoluble et du tamis moléculaire à échange d'ions métalliques non dissous ; et la quantification d'une teneur en métal dissous du mélange traité à l'aide d'une technique analytique appropriée.
