“…For this purpose, all samples were acidified with 3 M nitric acid and passed through a UTEVA resin to extract the analytes. 68 The resulting concentration of both Th and U in these samples was below the ppt level. Spikes were then added, followed by the calcium phosphate precipitation.…”

“…Memory effects have been reported during solution sample introduction with ICP-MS detection of U 67 and especially Th. 68 Even with ETV, it was necessary to read one blank signal after a high concentration solution (higher than 5 ng g À1 ) of analyte in order to avoid memory effects caused by incomplete vaporization. This does not occur for concentrations less than 1 ng g À1 .…”

Carbide formation was minimized using sample vaporization from a tantalum surface for U and additional use of tetrafluoromethane (Freon-23) as a gaseous modifier for Th and Pu. A prior Ca 3 (PO 4 ) 2 coprecipitation provided an enrichment factor of 50, yielding procedural detection limits (LOD) of 0.013, 0.029 and 0.017 pg g À1 for Th, U and Pu, respectively and corresponding absolute LODs of 0.13, 0.29 and 0.17 fg. Recovery of spikes from urine was typically 80%, whereas those from seawater, river water and biological materials averaged 99%. The accuracy of the method was validated by determination of U and Th in NIST SRM 1566b Oyster Tissue and U in a series of NRC natural water CRMs SLRS-4, CASS-4, NASS-5 and SLEW-3. Precision of determination was better than 10% at concentrations of 0.1 ng mL À1.

“…One study [16] has examined the utilization of various resins, including UTEVA (Eichrom), TRU (Eichrom), and AMBERLITE CG-400 (Sigma-Aldrich) for the separation of Th and U in natural samples. Furthermore, Grinberg and coworkers developed a sample preparation method for the analysis of lead using the UTEVA resin that achieved detection limits of 1.5 pg Th/g lead and 0.5 pg U/g lead [17]. The procedure consisted of a concentrated nitric acid digestion followed by evaporation, reconstitution in 3 M HNO 3 , and loading on UTEVA resin.…”

a b s t r a c tThis study describes a novel sample preparation and assay method developed, primarily in support of the MAJORANA DEMONSTRATOR neutrinoless double-beta decay experiment, for the determination of extremely low levels of Th and U in copper and lead shielding components. Meticulously clean sample preparation methods combined with anion exchange separations for analyte pre-concentration and matrix removal were developed. Quantification was performed by isotope dilution inductively coupled plasma mass spectrometry. Detection limits of 0.0084 pg 232 Th/g (0.034 mBq 232 Th/kg) and 0.0106 pg 238 U/g (0.131 mBq 238 U/kg) were determined for copper, while detection limits of 0.23 pg 232 Th/g (0.94 mBq 232 Th/kg) and 0.46 pg 238 U/g (5.7 mBq 238 U/kg) were achieved for lead. These methods allow the Majorana Collaboration to accurately assay detector components and ensure that the experiment's stringent radiopurity requirements are met.

“…The quantitative recoveries were also found after 20 cycles of column pretreatment procedures, which means that no loss of the activity and efficiency of the CCTS-DHBA resin after prolonged usage. This property is better than commercially available resin for uranium , UTEVA, in which the recovery of uranium decreased about 20% after 5 cycles [37].…”

A chitosan resin derivatized with 3,4-dihydroxybenzoic acid moiety (CCTS-DHBA resin) was newly synthesized for the collection/concentration of trace uranium by using cross-linked chitosan (CCTS) as base material, and the adsorption behavior of uranium as well as 60 elements on the resin was examined by passing the sample solutions through a mini-column packed with the resin. After the elution of the collected elements on the resin with 1 M HNO 3 , the eluates were measured by inductively coupled plasma-mass spectrometry (ICP-MS).The CCTS-DHBA resin can adsorb several metal cations and several oxoanionic elements at appropriate pH. Among these metal ions, uranium shows an excellent adsorption behavior on this resin. Uranium as UO 2 2+ species can be adsorbed on the resin by chelating mechanism with adsorption capacity of 330 mg g -1 resin. Through the column treatment, the complete removal of large amounts of alkali and alkaline earth matrices without any loss of adsorption efficiency over prolonged usage were achieved with this resin.The CCTS-DHBA resin was applied to the adsorption/collection of uranium in tap water, river water and seawater samples with satisfactory results. The validation of the proposed method was carried out by analyzing uranium in the standard reference materials of SLRS-4, CASS-4, and NASS-5 after passing through the CCTS-DHBA resin, and the results showed good agreement with the certified values.
