“…or any residue of organic matter are still present during the electrodeposition process, it will reduce the resolution of the peaks, leading to larger peaks than expected. In our work, the resolution of the peaks, given by the Full Width Half Maximum (FWHM), is between 25 and 37 keV for a counting efficiency of 24 ± 1%, which is somewhat better compared to other published methodologies [21].…”

Plutonium and americium are radionuclides particularly difficult to measure in environmental samples because they are a-emitters and therefore necessitate a careful separation before any measurement, either using radiometric methods or ICP-SMS. Recent developments in extraction chromatography resins such as Eichrom Ò TRU and TEVA have resolved many of the analytical problems but drawbacks such as low recovery and spectral interferences still occasionally occur. Here, we report on the use of the new Eichrom Ò DGA resin in association with TEVA resin and high pressure microwave acid leaching for the sequential determination of plutonium and americium in environmental samples. The method results in average recoveries of 83 ± 15% for plutonium and 73 ± 22% for americium (n = 60), and a less than 10% deviation from reference values of four IAEA reference materials and three samples from intercomparisons exercises. The method is also suitable for measuring 239 Pu in water samples at the lBq/l level, if ICP-SMS is used for the measurement.

“…The method first uses nitric acid -hydrofluoric acid to digest samples and remove silica, then uses an alkaline fusion to digest the samples, an iron hydroxide precipitation, followed by a cerium fluoride preconcentration step to remove the sample matrix and preconcentrate the actinides (Maxwell and Culligan, 2006). A version of this method to determine Pu and Am in 200 gram soil samples using acid leaching only was also reported (Maxwell and Culligan, 2008)., but a fusion of the soil leachate was still used in this process.…”

A new rapid method for the determination of 237 Np and Pu isotopes in soil and sediment samples has been developed at the Savannah River Site Environmental Lab (Aiken, SC, USA) that can be used for large soil samples. The new soil method utilizes an acid leaching method, iron/titanium hydroxide precipitation, a lanthanum fluoride soil matrix removal step, and a rapid column separation process with TEVA Resin. The large soil matrix is removed easily and rapidly using this two simple precipitations with high chemical recoveries and effective removal of interferences. Vacuum box technology and rapid flow rates are used to reduce analytical time.

A new rapid method for the determination of actinides in soil and sediment samples has been developed at the Savannah River Site Environmental Lab (Aiken, SC, USA) that can be used for samples up to 2 grams in emergency response situations. The actinides in soil method utilizes a rapid sodium hydroxide fusion method, a lanthanum fluoride soil matrix removal step, and a streamlined column separation process with
