Course objectives
The main task is to demonstrate the importance of speciation modelling, with the search in thermodynamic databases and work of software used for speciation calculations. In the framework of lecture, the study literature, databases and software will be made available for application in research and practice of new dynamically growing branches of chemistry (e.g. bioanalytical chemistry, material chemistry, environmental chemistry, etc.).
Syllabus
  • 1.Introduction. Importance of modelling in research and practice. Speciation - definition, examples, applications. 2. Theoretical knowledge for modelling of chemical processes in solutions. 3. Description of chemical processes in solution(acidobasic, precipitation, complex and redox equilibria and kinetics). 4. Metal ions in solutions. 5. Application of thermodynamic and kinetic data for modelling. Introduction with thermodynamic databases. 6. Influence of external conditions on thermodynamic and kinetic data (temperature, ionic strength, pressure, etc.) 7. Equilibria in solutions of polyelektrolytes. Examples(the models of protonation and complexation of metal ions by bioligands, e.g. sugars, lignins, fulvic and humic acids). 8. Interphase equilibria solution-gas, solution-solid. Examples (silicates, carbonates, etc.). 9. Experimental methods for determination of chemical species equilibrium concentrations (speciation). 10. Numerical methods for calculation of equilibrium concentrations and their application in species calculation under equilibrium and non-equilbrium conditions. 11. Demonstration of software for calculations.
