Sr in urine sample; Rapid separation of Sr by phosphate co-precipitation and extraction chromatography, followed by determination by triple quadrupole inductively coupled plasma mass spectrometry (ICP-MS/MS)Tomita, Jumpei; Takeuchi, Erina
Applied Radiation and Isotopes, 150, p.103 - 109, 2019/08
Times Cited Count：14 Percentile：82.61(Chemistry, Inorganic & Nuclear)A rapid analytical method for determining Sr in urine samples (1-2 L) was developed to assess the internal exposure of workers in a radiological emergency. Strontium in a urine sample was rapidly separated by phosphate co-precipitation, followed by extraction chromatography with a tandem column of Pre-filter, TRU and Sr resin, and the Sr activity was determined by ICP-MS/MS. Measurement in the MS/MS mode with an O
reaction gas flow rate 1 mL min
showed no tailing of 
Sr at m/z = 90 up to 50 mg-Sr L. The interferences of Ge, Se and Zr at m/z = 90 were successfully removed by chemical separation. This analytical method was validated by the results of the analyses of synthetic urine samples (1.2-1.6 L) containing a known amount of Sr along with 1 mg of each of Ge, Se, Sr and Zr. The turnaround time for analysis was about 10 h, and the detection limit of Sr was approximately 1 Bq per urine sample.

-irradiated in urea canal complexes by addition of various solventsYoshii, Fumio; Kaetsu, Isao

Times Cited Count：0Post-polymerization by the addition of various solvents to long chain monomers after irradiation in the urea canal complexes was investigatThe polymerization occurred nearly quantitatively by the addition of highly viscous solvents, more easily than by the addition of cooled methanol. This post-polymerization occurs when the monomers are released by the dissolution of the urea canal. It is deduced that the decreased termination rate and the increased life-time of growing chain radicals in high viscosity solvents increase the polymerizability of monomers.
