This subject extends the theoretical knowledge of the used analytical methods and the processing of the obtained results through mathematical simulation of experimental results in the field of wet-path analysis (classical and instrumental titration) and instrumental analysis (spectroscopy, extraction, chromatography) with the aim of deepening knowledge about possible sources of uncertainties and systematic errors of measurement results. The theoretical interpretation (1/3 of the scope) is complemented by a separate work on projects and individual consultations of their solutions. Existing software, mainly MS Excel, but also Matlab / Octave, and R statistics will be used in solved examples and can be applied for projects solving.
Aim of the course -
Last update: Pátková Vlasta (16.11.2018)

Students will be able to

  • qualitatively and quantitatively describe the composition of the water system influenced by protolytic, complexing, precipitating and redox equilibria
  • design and evaluate experiments to obtain conditional complex stability constants and information on their stoichiometry
  • use mathematical models to fit experimental data, deconvolute overlapping signals, and estimate model parameter uncertainties
