Invitation to the lecture "Capillary Electrophoresis for Study of Complex Formation in Solution" by Dr. Vladimir SLADKOV Research Associate CNRS , Institute of Nuclear Physics, Orsay, France Anotation: This presentation will be devoted to the investigation of chemical equilibiria between metal ion and inorganic (organic) ligand in the aqueous solutions by affinity capillary electrophoresis. Several systems will be examined: U(VI)-Se(IV), U(VI)-Se(VI)… The influence of the pH, the ionic strength and the temperature will be discussed. The cases of the systems with different kinetics (rapid, intermediate and slow) will be also treated. Scientific interest: Speciation of heavy metals, actinides and fission products in different media in relation with nuclear fuel cycle by capillary electrophoresis and time-resolved laser induced fluorescence spectroscopy Determination of actinide ions and organic acids in different media: application for nuclear fuel dissolution study Some selected publications: Sladkov, V., Y.
