Magnesium, solvent exchange data

Table IV shows the results of three laboratory runs of the solvent extraction step (after the plutonium was removed by anion exchange). The major elements are shown before solvent extraction, after solvent extraction, in the 7M HNO wash, and in the final strip product. The americium remaining in the organic after stripping is also shown. Although there were some analytical discrepancies, the data show that americium was effectively recovered (except in Test 1, for which we have no explanation). Americium was decontaminated from aluminum and magnesium in all three runs.
