Progress in Rhodium Determination Method for Rhodium-containing Materials

Rhodium has been known for the good catalytic capability due to its unique electronic structure, and rhodium-based catalysts are used in the fields of environmental protection, petrochemical processing, fine chemical industry, biopharmaceutical, etc. The catalytic efficiency of rhodium catalysts is affected directly by rhodium content. As a result, accurate determination of the rhodium content is especially important. Methods for the determination of rhodium in rhodium catalysts of different types and varied contents are reviewed in the present paper.
