Abstract
Three radionuclide-spiked salt solutions have been prepared that simulate a range of typical compositions in Savannah River Site waste solutions. The Savannah River National Laboratory performed a series of tests with the three salt solutions designed to determine the propensity of ammonium molybdophosphate (AMP) to bind some of the common analytes such as the actinides (Pu, Am, Np, U), strontium, or the elements (Ag, As, Ba, Cd, Cr, Hg, Pb, Se) regulated by the Resource Conservation Recovery Act (RCRA). The results of the tests indicate that within the protocol conditions, AMP exhibited no appreciable affinity for plutonium, neptunium, uranium and strontium. AMP showed a possible minor affinity for americium; however, the data is not as clear due to continued americium solubility changes during the duration of the experiment. Of the eight RCRA elements studied, AMP exhibited affinity for only silver under our experimental conditions.
