“…There is an increasing need to develop faster analytical methods for emergency response, including emergency soil and air filter samples [1,2,3]. There are a number of 3 analytical methods reported that use ion exchange/extraction chromatography plus alpha spectrometry to determine actinides in soil.…”

“…ICP-MS is particularly effective for longer-lived actinide isotopes, where alpha spectrometry works well for short-lived actinide isotopes. Alpha spectrometry cannot differentiate between the alpha isotopes with overlapping alpha energies, such as 239 Pu and 240 Pu, which are easily differentiated by ICP-MS. Actinide determination by ICP-MS can be hampered by isobaric, polyatomic interferences and signal suppression [5] . Both measurement techniques may require separation of interferences to determine actinide isotopes accurately, depending on the sample matrix and the detection limit required.…”

“…Epov at al reported an automated preconcentration system using TRU Resin, but indicated that the separation of uranium 4 from plutonium was not complete [7] . Lariviere et al reported an automated flow injection system using TEVA Resin with chemical yields averaging 83% for 10 ml urine sample aliquots, but when a co-precipitation step was added for larger sample aliquots, the chemical yield for Pu dropped to approximately 70% [5] . This system was effective, but this work was limited to plutonium separation only.…”

A new rapid separation method that allows separation and preconcentration of actinides in urine samples was developed for the measurement of longer-lived actinides by inductively-coupled plasma mass spectrometry (ICP-MS) and short-lived actinides by alpha spectrometry; a hybrid approach. This method uses stacked extraction chromatography cartridges and vacuum box technology to facilitate rapid separations. Preconcentration, if 2 required, is performed using a streamlined calcium phosphate precipitation. Similar technology has been applied to separate actinides prior to measurement by alpha spectrometry, but this new method has been developed with elution reagents now compatible with ICP-MS as well. Purified solutions are split between ICP-MS and alpha spectrometry so that long and short-lived actinide isotopes can be measured successfully. The method allows for simultaneous extraction of 24 samples in less than 3 hours (<7.5 minutes per sample).The simplicity and speed of this new method makes it attractive for radiological emergency response. If preconcentration is applied, the method is applicable to larger sample aliquots for occupational exposures as well. The chemical recoveries are typically greater than 90%, in contrast to other reported methods using flow injection separation techniques where plutonium yields were 70-80%. This method allows measurement of both long-lived and short-lived actinide isotopes. 239 Am, 243 Am and 244 Cm were measured by alpha spectrometry. The method can also be adapted so that the separation of uranium isotopes for assay is not required, if uranium assay by direct dilution of the urine sample is preferred instead. Multiple vacuum box locations may be set-up to supply several ICP-MS units with purified sample fractions such that a high sample throughput may be achieved, while still allowing for rapid measurement of short-lived actinides by alpha spectrometry.

The importance of rare‐earth elements (REEs) in the global economy is booming as they are used in numerous advanced technologies. Industrially, the extraction and purification of REEs involve multiple liquid–liquid extraction (LLE) steps as they exhibit very similar complexation properties with most common ligands. In order to substantially improve this process and provide a greener alternative to LLE, functional porous hybrid materials, demonstrating enhanced selectivity towards heavier REEs compared to commercially‐available products, are proposed. In addition, because of the grafting procedure used in the synthesis, the proposed materials demonstrate a higher degree of reusability, increasing their marketable potential.
