Syllabus
  • The aplication of analytical methods in geology. Specific problems during the analyses of rocks. The applicability and testing of the methods. The standards of rocks. Analytical errors, their behavior - the influence of number operations. Precision and validity of the methods. Detection and determination limits. Computations. The data handling and presentation.

    The sample praparation. Rock sampling. Crushing and grinding. Contamination and changes in composition. Quartation. Weighing. Dissolution of rocks in acids. Basic, acidic and oxidation fusion. Stock solutions, aliquots. Problems and errors.

    The choice of methods. Topical analytical methods. Destructive and non-destructive methods. Chemical and instrumental methods. Suitability of method. Sensitivity, precision. The ratio precision/charge of determination.

    Topical chemical methods. Gravimetrical determination of high contents of S, Si, H2O, CO2. Complexometric determination of high contents of Al, Ca, Mg. Acidimetric determination of high contents of B, Si. Oxidimetric determination of Fe(III), Fe(II). Extraction, ion-exchange resins, chromatogaphy, ultrafiltration, centrifugation, masking.

    Emission spektrometry: Total qualitative and semiquantitative analyses of geological materials by OES. Determination of Li, Na, K, (Ca, Ag, Al...) by flame spectrofotometry. Determination of low concentrations of metals and some non-metals by ICP, advantages, problems, aplications. X-ray methods: Total analyses of silicates by X-ray fluorescence (energy and wave dispersion), aplications, advantages.

    Absorption spektrometry: Determination of low concentrations of metals (Cu, Zn, Mg, Ca, Sr...) by AAS (flame version, ETA), advatages, problems, aplications. Determination of low concentrations of elements (Fe, Ti, Si...) by molecule absorption spectrofotometry, advatages, problems, aplications.

    Special methods. Neutron activation analyses. Analyses of mineral surfaces (AES, XPS, ERD, RBS, SIMS). Infrared spektrometry, geological aplications. Mass spectrometry, determination of stabile isotopes. NMR, ESR methods.

    Electrochemical methods. Electrodes. Monitoring of Eh and pH. Determination of elements (F, Ca, Na...) by ion-selective electrodes, indication of equivalence point during titration, continual monitoring. Polarographic determination, anodic stripping voltammetry, limits of determinations, environmental aplications. Tribo-polarograph.
