Detection of precious metal catalysts
Thread Content
Nowadays, precious metal catalysts are being used in an increasingly wide range of applications. Apart from the IGP method, are there any other simple and rapid methods for detecting the content of precious metals in catalysts?
Atomic absorption spectroscopy (AAS) or X-ray fluorescence spectroscopy (XRF) can be tried. Both of these methods can accurately measure the content of precious metals quickly. .
They’re talking about buying some gun that, when fired, will release all kinds of elements; P
For a rough quantitative analysis, X-ray fluorescence spectroscopy can be used to determine the approximate content of precious metals in the catalyst. If a more accurate analysis is required, some molecular or atomic spectroscopic analysis methods can be used. If a very in-depth analysis is desired, capacity analysis can be employed, such as complexometric titration ； Or Coulombic analysis from electrochemistry can be employed, such as electrolytic deposition
