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.
