Direct determination of cesium in pilot plant effluents by isotope dilution mass spectrometry

Description: At the Savannah River Laboratory, stable cesium at the part per billion levels is routinely determined in simulated defense waste supernate by isotope dilution mass spectroscopy. This work is in support of pilot plant studies of waste immobilization process. A direct method was developed in which spiked samples of simulated waste supernate are loaded directly on the sample filament.

Analytical methods for the determintion of some elements and Fe/sup +2/ to Fe/sup +3/ ratio in simulated sludges and Synroc formulations

Description: Analytical methods for the determination of Fe, Al, Mn, Ca, Ni, Na, Sr, Cs, Ti, and Ba in simulated sludges and Synroc formulations are discussed. These are the elements that may be completed by atomic absorption spectroscopy, AAS. AAS methods are complicated by the dissolution methods used. These problems are discussed. In addition, the method used for the determination of Fe/sup +2/ to Fe/sup +3/ ratio is presented.
