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 reviewed LIBS methods for a liquid phase to improve detection sensitivity. We
performed LIBS measurements with the sheet flow for the simultaneous determination of elements in
simulated high-level radioactive waste liquid and discussed the application potential as a tool for online
process monitoring.
