Application of laser-induced breakdown spectroscopy method for elements analysis of metal ions in an aqueous solution in nuclear reprocessing process control

Oba, Hironori; Saeki, Morihisa; Wakaida, Ikuo 

Laser-induced breakdown spectroscopy (LIBS) is an attractive technique for determining elemental composition in real time, in-situ and remotely without any sample preparation. The LIBS analysis of metal ions in an aqueous solution is available in process control and environmental monitoring. In the present paper, we have reviewed the LIBS methods for a liquid phase that tried to improve the detection sensitivity. We have performed the LIBS measurement with the sheet flow for the simultaneous determination of elements in the simulated high-level radioactive waste liquid and have discussed on the application possibility as a tool for online process monitoring.
