Popis: | Rapid analysis of 90Sr in bone and tooth samples of cattle was achieved by inductively coupled plasma mass spectrometry (ICP-MS) coupled with mass-shift and solid-phase extraction techniques. The mass-shift technique with the O2 reaction mode of ICP-MS was applied to the mass shift of isobaric element 90Zr, effectively removing its interference. The solid-phase extraction technique using a Sr resin, which is a polymeric resin supported by 4,4′(5′)-bis-t-butylcyclohexano-18-crown-6, quantitatively separated 90Sr from the interfering matrix elements and isobars in the bone and tooth samples. The activity concentrations determined by ICP-MS were comparable with those determined by the conventional radiometric method. However, the limit of detection in the ICP-MS measurement of 0.1 g samples was lower than that in the radioactivity measurement. The analytical time of the ICP-MS method was shortened from 20 days to 11 h, compared with the radiometric method. Therefore, the ICP-MS method can be a rapid and useful procedure for determination of 90Sr in small bone and tooth samples taken from terrestrial animals. |
