“…The overall chemical fractionation between 237 Np and 242 Pu for the whole analytical procedure was 0.974 AE 0.064 (k ¼ 2), allowing 237 Np and Pu isotopes to be measured using 242 Pu as a yield tracer with yields of 76 AE 5%. The ICP-MS/MS LODs were 0.025, 0.025, 0.015, and 0.020 fg mL À1 for 237 Np, 239 Pu, 240 Pu and 241 Pu, respectively, for a 20 mL urine sample. The method was validated by the analysis of three Pu-spiked urine reference materials from the Association for the Promotion of Quality Control in Radiotoxicological Analysis (PROCORAD), France, and by comparison of results with those obtained by conventional alpha spectrometry.…”

“…The method was validated by the analysis of three Pu-spiked urine reference materials from the Association for the Promotion of Quality Control in Radiotoxicological Analysis (PROCORAD), France, and by comparison of results with those obtained by conventional alpha spectrometry. The procedure developed successfully measured the concentrations of 237 Np, 239 Pu, 240 Pu, and 241 Pu in urine samples collected during decorporation therapy with DTPA, following a Pu inhalation exposure accident in Japan. The researchers concluded that the method developed (twelve 20 mL samples in 9 h) was superior to the alpha spectrometry method, that required 500 mL of sample and took one week for 2 samples.…”

Thallium is a water-soluble metal and extra dosage has toxicological effect in human body. Thallium is readily absorbed by inhalation, ingestion and skin contact. The symptomatology of thallium toxicity was seen in patients with hemorrhage, bone/gastrointestinal problems, delirium, convulsions and coma. So, accurate determination of thallium in water and human urine is necessary. In this research, a novel and applied method based on 25 mg of nanomagnetic 4-Aminothieno[2,3-d] pyrimidine-2-thiol functionalized on graphene oxide (Fe3O4-ATPyHS@GO) was used for thallium extraction in 50 mL of water, wastewater and urine samples by dispersive magnetic micro solid-phase extraction (DM-μ-SPE). After extraction and back-extraction of solid phase by 1 mL of nitric acid solution, the concentration of thallium ions determined by flame atomic absorption spectrometry (F-AAS). The working/linear range, the limit of detection (LOD), and preconcentration factor (PF) were achieved (4-1400 μg L−1; 4-300 μg L−1), 0.9 µg L−1, and 50, respectively (Mean RSD%=1.8 water; 2.1 urine). The absorption capacity of Go and Fe3O4-ATPyHS@GO adsorbent were achieved 7.2 and 137.5 mg g-1 for 5 mg L-1 of thallium, respectively. The procedure was validated by ICP-MS analyzer.
