The extraction behavior of 212Pb, 197mHg, and 194Au on TEVA resin in HCl and HNO3 solutions was studied with batch uptake, kinetics, and column studies. The uptake of mercury and gold was extremely high from HCl solutions, with maximum k’ >80,000 for both elements. The uptake of mercury was lower in HNO3 than HCl with a maximum k’ of ~ 8,000 in 0.02 M HNO3 and decreasing uptake at higher concentrations of HNO3, which agrees well with previous work. The batch uptake of gold in HNO3 was not measured, as it had been reported previously. The uptake of lead on TEVA resin in HCl was low with a maximum k’ of only ~ 90 in 1 M HCl. The uptake of lead in HNO3 was negligible. The uptake kinetics of gold and mercury were characterized in HCl and HNO3 solutions and high uptake was seen after ~ 60 s for both elements. Column separations of 212Pb, 197mHg, and 194Au on TEVA resin from HCl and HNO3 solutions are reported with high yields of mercury and lead, but with high losses of gold, which is retained on the resin. A rapid, high yield separation of 197mHg from irradiated gold foils is presented with yields of ~ 100% for both elements and a total separation time of < 2 h.
