| titleOfInvention | Separation reagent of platinum group metal, method for separating and recovering platinum group metal, and amide-containing tertiary amine compound |
| abstract | The present invention provides a novel separation reagent capable of obtaining a high extraction % of rhodium in a chlorine-based acid solution, which has never existed heretofore, and a method for separating and recovering a platinum group metal using the same. An organic phase composed of an amide-containing tertiary amine separation reagent represented by the structural formula shown below is brought into contact with an acid solution containing a platinum group metal, thereby extracting rhodium, platinum and palladium with the organic phase. Among the metals extracted with the organic phase, rhodium is selectively back-extracted with a highly-concentrated hydrochloric acid solution, while palladium and platinum are back-extracted with a highly-concentrated nitric acid solution: n nwherein at least one of R 1 , R 2 and R 3 represents an amide group represented by:n n nR 1 to R 3 other than the amide group and R 4 to R 6 represent a group selected from an optionally branched chain hydrocarbon group of 1 to 18 carbon atoms, an alicyclic hydrocarbon group of 1 to 10 carbon atoms, and an aromatic hydrocarbon group of 1 to 14 carbon atoms. |
