Application of Laser-Induced Breakdown Spectroscopy Method for Elements Analysis of Metal Ions in an Aqueous Solution in Nuclear Reprocessing Process Control

Abstract

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.
