Course objectives
Main objectives can be summarized as follows:
the knowledge of all aspects of geochemical experiments under ambient conditions, especially:
preparation of mineral phases and solutions
experimental arrangement and construction components - reactors
mathematical analysis of the reactors
modeling of the basic processes running in reactors
field experiments
some laboratory experiments under extremely conditions
practice on experimental instrumentation in geochemical laboratory
Syllabus
  • Experiment in earth sciences: Observations and data collecting. The development of theories and hypotheses. Models. Verifications. Experiment. Geochemical experiments.
  • Preparation of solids for experiment: Crushing, grinding, sieving fractions, separation, homogenization.
  • Surface of minerals and rocks: Ageing and cleaning of surfaces (sonic, magnetic, by decantation, by dissolving of superfine particles, relaxation of surface defects), influence on dissolution kinetics, measurement and estimation of surface area, BET method.
  • Preparation of experimental solutions: Concentration, activity, ion strength, buffers, ion-exchangers
  • Transport of liquids: Hydrostatic reservoirs, peristaltic pumps, "bubble" transport
  • Measurement of parameters: Electrodes for pH and Eh measurement, ion-selective electrodes, electrochemical and spectral methods.
  • Detectors: Universal and selective detectors. Refractometric-, high/frequency-, polarographic-, conductivity measuring-, optical-, spectral-, and spectrophotometrical- detectors.
  • Reactors: Batch and flow-through reactors, features and behavior, block diagrams, designing of apparatus. Discontinuous flow-through reactor.
  • Construction constituents and materials: Glass, plastics, ceramics, metals, properties, prices.
  • Modeling of processes in reactors: Thermodynamic and kinetic models, computer and numeric modeling.
  • Landscape-experiments: Kinetic experiments, mass balance in catchments.
  • High-temperature experiments: Materials, technical possibilities, attainable temperatures and pressures.
