Tracer Investigation of Iridium-Platinum Separation by Anion Exchange

The separation of 10-mg quantities of iridium and platinum by the use of Dowex A-I anion resin has been investigated using radiotracer techniques. Elution curves are exhibited for iridium(III), platinum(II), and platinum(N) recovery from resin columns, and a procedure is reported for the rapid separation of iridium and platinum. (auth)
