The half-life of 181W

Isotope and Nuclear Chemistry Division annual report, FY 1983

“…• Real-time metabolic information in living tissues was obtained for microorganisms and perfused organs of Small animals by use of 13 C NMR. • An improved procedure for the separation of 52 Fe has been developed and involves anodic oxidative dissolution in HC1 followed by separation on a tributylphosphate-coated silica gel column.…”

“…The next day an extraction was performed en the lead nitrate solution to remove tungsten. The extraction was similar to one used by Meyers and Nagle, 52 which employed a-benzoinoxime in CHCI3. Tungsten was removed from the dissolved target in the organic phase.…”

“…To overcome the limitations of HN0 3 dissolution for recovery of 52 Fe from proton-irradiated nickel targets, we developed an anodic dissolution technique that results in a HC1 solution. The nickel target disks are supported on a platinum wire, which is the anode of an electrolytic cell.…”
