NECTAR for highly hydrolysable (HHC) and/or low-valence state (LVC) cations
Equilibrium analysis of systems containing highly hydrolysable or low-valence state cations is always very challenging.
Typical bottlenecks, inadequate for the interpretation of phenomena at specific conditions, are:
- Difficult experimental set-up (e.g., formation of sparingly soluble species for HHC, oxidation for LVC in the presence of traces of dioxygen or other oxidants, etc.).
- Lack of reliable literature data (e.g., unreliable speciation models, missing and/or questionable thermodynamic parameters, literature discrepancies, etc.).
- Narrow ranges of experimental conditions explored to date (e.g., temperature, ionic media and ionic strengths, presence of competing ligands, etc.).
Defining precise strategies for the study in solution of systems containing HHC (e.g., Zr(IV), lanthanoids, actinoids, oxoions).
Defining procedures and experimental approaches for the study of LVC (e.g., Fe(II), Sn(II), Cu(I)), especially those spectroscopically silent (e.g. Cu(I)).
Providing protocols for the study of the speciation of HHC and LVC under conditions of interest for biological, environmental and technologically/industrial applications.
Providing reliable, accurate and comprehensive sets of thermodynamic data of systems containing HHC and LVC in a wide range of different experimental conditions.
Determination of the hydrolysis constants (and other thermodynamic parameters) of HHC and LVC.
Study of complexes of HHC and LVC: speciation, solubility, kinetics of formation, redox properties.
Structural study and correlation of structural information of the complexes with solution properties.
Modelling of the speciation of the complexes as a function of different conditions (e.g., total cation concentration, pH, pe, ionic strength, system composition, temperature).
Validation of data through interlaboratory and blind round-robin experiments to check reliability and consistency of results obtained.
Dissemination of results, especially those related with experimental procedures.
