Title: A process for the purification of rhodium
IPC: C01G49/00
Filed: 1949-07-08
Abstract: An aqueous solution of a water-soluble complex rhodium salt in which rhodium is present in the anion, or a water-soluble complex rhodium acid, in which the concentration of the salt or acid is up to 0.1M is treated with a cation exchange resin containing a sulphonic acid group to remove impurities.  Suitable rhodium compounds are potassium, sodium and ammonium hexachlororhodate, the free acid H3 (RhCl6), potassium and ammonium aquopentachlororhodates, the corresponding bromorhodates, and the nitrite analogues in the case of the sodium salt and free acid. Suitable resins are "Zeo-Karb" 215 (Registered Trade Mark), Dowex 50, Dowex 30, Wolfatit KS, sulphited phenol-formaldehyde resins, and sulphonated lignite types of resin. The compositions of these resins are indicated, Specification 498,251 being referred to.  Treatment is effected at pH 1-5.  The resin containing the metal ions is regenerated by treatment with 2N H Cl. The purified rhodium solution may be treated with ammonium chloride and the ammonium salt produced ignited to the metal. Alkali or alkaline earth metal hexachlororhodates for subsequent reduction to rhodium may also be produced.ALSO:In a process for the purification of rhodium, ammonium hexachlororhodate is ignited in air, and the metal produced is treated with hydrogen fluoride for the removal of silica. Alternatively, rhodium is recovered from alkali or alkaline earth metal hexachlororhodates by treating with hydrogen at elevated temperature followed by leaching out of the alkali or alkaline earth metal chlorides; or the rhodium may be separated from the alkali or alkaline earth metal compounds in aqueous solution by means of a reducing agent such as formic acid.
