Measurement of 90Sr by Preconcentration/Matrix Separation and Reaction Cell ICP-MS
نویسنده
چکیده
The tsunami after the 2011 Tohoku earthquake devastated a vast coastal area of eastern Japan. The Fukushima Daiichi nuclear reactor suffered meltdowns of its uranium fuel rods, resulting in the release of radioactive isotopes. One of the most environmentally critical isotopes released was strontium-90 (90Sr), a fission product of uranium and plutonium which has a half-life of 29 years, thus remaining in the environment for a significant amount of time. 90Sr itself decays into yttrium-90 (90Y), followed by decay into stable zirconium-90 (90Zr). When organisms ingest 90Sr, it accumulates in the bones and continues to emit beta radiation. Therefore, assessing 90Sr contamination in the environment is urgently needed for local public health concerns.

Zr and U determination at trace level in simulated deep groundwater by Q ICP-MS using extraction chromatography.
In the framework of trace element analysis by Q ICP-MS in a simulated deep Callovo-Oxfordian groundwater, separation procedures based on extraction chromatography were developed to eliminate the high salt contents and to concentrate Zr and U simultaneously. Theoretical and experimental speciation studies showed the importance of adjusting the medium to HNO₃/HF (0.5 M/0.005 M) to guarantee the s...

A separation and preconcentration method based on solid-phase extraction using sulfoxide adsorbent was developed for the determination of Hg(II) in natural water samples by inductively coupled plasma mass spectrometry (ICP-MS). The sulfoxide adsorbent was packed into a commercially available syringe-driven column (with a bed volume of 1.0 mL), which permitted off-line sample loading and on-lin...
