Ion Exchange Characteristics or Platinum Group Metals by Ion Exchange Resins
High-level wastes contain significant quantities of platinum metals such as palladium, ruthenium, and rhodium. These metals are used for catalystic process, electronic and electrochemical industries, anti-corrosion alloys, dental applications etc. The demand of noble metals continues to grow in a steady manner. Many techniques for separation and recovery of the platinium group metals have been studied. In this paper, batch experiments were carried out to investigate ion exchange characteristics of platinum group metals by commercial anion exchange resins such as IRN 78 and Dowex 1x8. The effects of ionic group of resins, solution temperature, co-ions, and the concentration of nitric acid were investigated.
