| Abstract: | Solvent extraction behaviour of iridium(lll) with salicylhydroxamic acid (SHA) in iso-butanol from aqueous chloride solution has been studied and compared with similar extraction behaviour of rhodium(lll) and ruthenium(lll). The overall extraction equilibria for the three systems can be expressed by the followingsingle generalised equation: M3+ + 3HL(0) Ml3(0)+ 3H+. The effects of aqueous phase pH, metal ion concentration, chloride ion concentration and the reagent concentration in the bulk organic phase on the extraction of iridium are discussed. The possibility of separation of iridium from rhodium and ruthenium has also been investigated. |
