UOP 873 – Noble Metals and Modifiers in Catalysts by ICP-AES
This method is for determining platinum rhodium and rhenium in fresh and regenerated catalysts composed of alumina or silica/alumina by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES). Additionally modifiers such as tin indium lithium potassium cerium and lanthanum can also be determined. Platinum and rhenium can be determined within the concentration range of 0.1 to 1.0 mass-% when a 1-g sample of catalyst is used for the analysis while rhodium can be determined down to 0.01 mass-%. The tin indium and lithium concentration range is generally 0.1 to 0.7 mass-%. Potassium cerium and lanthanum can be determined from 0.5 to several mass-%. The method is sufficiently flexible to add more elemental analyses if needed.
