Catalyst characterization Recyclability Reusability Catalyst leaching How is it possible to calculate catalyst leaching? is it enough to use gravimetric method?
If you can wash catalyst effectively it can be usable. In addition ICP analysis of possible ions in reaction solution may help you.
The method used normally in the leaching tests is related to the nature of the catalyst you are using. if you are using supported metal catalysts and you want to measure the amount of the metal leached during you reaction, you can separate your catalyst at the end of your reaction and conduct an ICP-OES analysis either for the filtrated catalyst or for the reaction solution after the separation of your catalyst. Please notice that if the leached metal in the reaction solution was in nano particle form you might not be able to determine its content in the reaction mixture using direct injection in ICP-OES. In this case you have to dissolve your metal inside the reaction mixture prior to the ICP-OES analysis. In the end you can find some answers for a slimier question in the following link:
