Abstract
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.
