Analýza jílových minerálů s vysokým obsahem interkalovaných prvků metodou rentgenové fluorescenční spektrometrie

Abstract

This diploma thesis deals with development of method for precious determination of silver content in clay minerals (vermiculite, montmorillonite) intercalated with silver. To analyze all prepared samples was used x-ray fluorescence spectrometry. Due to the unavailability reference materials of clay minerals with a high silver content were prepared by their own highly homogenous reference materials. Method was used to melt the samples with di-lithium tetraborate. With those of reference materials were constructed two calibration models for XRFS. Using the new calibration models were measured real samples intercalated with silver and was demonstrated, that newly created methods for determination of silver are suitable for determination of silver content in samples.
