The 191Pt-radiotracer is a powerful tool to develop separation and preconcentration methods for Pt. The radiotracer was produced either through 190Pt (n, gamma) 191Pt reaction on Pt enriched in 190Pt, or through 191Ir (p,n) 191Pt reaction on natural Ir, followed by Pt/Ir separation. The solvent extraction behavior of 191Pt(IV) from HCl with tributylphosphate, rubeanic acid in tributylphosphate and thenoyltrifluoroacetone in n-butylalcohol/acetophenone, followed by back-extraction with 2 mol/L NH4OH was studied. The overall recovery from a biological matrix is up to 80%. Trace amounts of 191Pt were also preconcentrated as bis-(carboxymethyl) dithiocarbamate chelates on an XAD-4 microcolumn and eluted with EtOH/1 mol/L HNO3. More than 80% is recovered in 2 mL or about 70% in 300 microL.
