More Information
  • Received Date: January 26, 1992
  • The paper describes a determination method of Ru. Rh and Pd in HLLW with cation-exchange separation and ICP-AES measurement. A sample of HLLW was treated with the hydrochloride acid containing enough sodium chloride, then passed through a strongly acidic cation-exchange resin col umn, the Ru, Rh and Pd as ehloro-complexs go to the eluate while the interference elements are ab sorbcd on the resins in the column. The Ru, Rh and Pd are collected and determined by ICP-AES. The obtained results show that the recovery is 90% and the relative standard deviation is 6% as the Ru con tent within the range (35—230)×10~(-6) the recovery is 106% and RSD is 10% as the Rh content within (2 20)×10~(-6); and the recovery of Pd is 72% as its content less than 2×10~6.
