T. H. Al-Noor Thank you for the link, but I failed to find the paper on the page. May you please share the DOI of the publication.

Thanks

Thanks for Your kind explaining. I understood, that the method you are using is the adsorption of cerium ions or charged cerium colloids in the electrical double layer at the catalyst's surface. Normally, this kind of reactions proceed rather fast as nearly all ion exchange reactions do. You could proof by measuring the time dependence of cerium concentration in the liquid phase by polarography.
