A new approach for determining stability constants of metal ion complexes in aquatic systems based on flow injection-ion exchange-flame atomic absorption spectrometry coupling
(Gordon Breach Sci Publ Ltd, 1997-01-01)
A method based an ion exchange(IE)-atomic absorption spectrometry(AAS) coupled by flow techniques, allowing the determination of formation constants of, at least, the first species of complex systems, in aqueous solution, ...
Er-doped silica-based waveguides prepared by different techniques: RF-sputtering, sol-gel and ion-exchange
(Kluwer Academic Publ, 2002-12-01)
Erbium-activated silica-based planar waveguides were prepared by three different technological routes: RF-sputtering, sol-gel and ion exchange. Various parameters of preparation were varied in order to optimize the waveguides ...
