A separation procedure was developed and implemented for the isolation of gold (Au) and platinum (Pt) radionuclides from deuteron irradiated Pt using tri-butyl phosphate (TBP) resin. Computational modeling and experimental results of the Au and Pt radionuclide production were reported and compared to literature values. Results of the separation procedure demonstrated a Pt recovery of 98 ± 2% and a Au recovery of 92 ± 7%, in their respective fractions ( n  = 4 ± 1 σ ) The decontamination factors were 2900 ± 500 for Au removal from the Pt fraction and 830 ± 30 for Pt removal from the Au fraction ( n  = 4 ± 1 σ ).
