RESEARCH AREAS
equilibrium and spectroscopic data treatment
The main topics covered in this research line include the study of ionic equilibrium using several techniques (potentiometry, absorption and fluorescence spectrometry, liquid chromatography and capillary electrophoresis), applied to different equilibrium systems in:
- aqueous and non-aqueous media
- micellar media
- liquid-liquid extraction
- liquid-solid partition
In some cases, new operational procedures and software needed for the proper data treatment have been developed within this research line.
On the other hand, some chemometric procedures have been applied for the prediction of drug properties (PLS) and the characterization of dissolved organic matter in water by Excitation-Emission Fluorescent spectrometry (PARAFAC).
