Course objectives
The course deals with the relatively young branch of earth sciences - with experimental geochemistry. There are discussed all aspects of geochemical laboratory experiments under ambient conditions, the rock-water interactions especially. It focuses on the preparation of mineral phases and solutions, on reactors, experimental arrangement and construction components. All types of reactors are mathematically analyzed. The basic processes progressing in reactors are modeled. In addition, field experiments and some laboratory experiments under extremely conditions are discussed theoretically. Students are familiarized with 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.
