Spéciation du cuivre en milieu hydrothermal profond et dans les zones de suintements froids
Provedor de dados: 5
Autores: Aumond, Virginie.
This work presents the copper speciation in the deep ocean and the exchanges existing between different size fractions : particulate, dissolved and colloidal. It focus on the mixing zone between deep sources and seawater. The enhancement of our knowledge and the optimization of instrumentation make possible the development of sampling and analysis strategies accorded with the nature and the accessibility of these extreme environments. A part of this work consisted in the development of effective analysis methods for the quantification of copper and copper’s ligands. Our results showed that physical speciation seems to be essentially controlled by the variations of pH and oxydoreductive caracteristics during the dilution of the hydrothermal fluid by...
