Study and development of the laser induced breakdown spectroscopy (LIBS) for the realization of field measurements : application to analysis on-line of metals in liquids
type: Dataset
description: Metal contamination of water is a major public health issue. Controls and treatments are more drastic and performed on them for human consumption. It is essential for this to possess reliable and sensitive analytical tools adapted to the existing regulations and flexible enough to use. The technique of "Laser Induced Breakdown Spectroscopy" (LIBS), proven for the analysis of solids, including exo-terrestrial explorations, this very interesting advantages for liquids including, for example, are multi-character elementary and the possibility of in-situ measurements of water contamination by metals.A first part of this study thesis allowed to explore the potential (LIBS) for the analysis of dissolved metals or suspensions in water. Study has found an important effect related to the particle size in the analysis of suspensions. A second prong is to look at the effects of organic matrix represented by humic acid and those natural minerals represented by the bentonite and alumina particles. The matrix effect observed was corrected by normalization by internal standard.
