| Popis: | Iron is one of the most abundant elements on Earth and also in Mössbauer research. The present study is a summary of our search for iron compounds that now play an important role in the development of specific areas of inorganic chemistry of iron, biological applications and pigment for various types of artworks. The different catalytic or biologically active systems were studied in particular of the Mössbauer spectrometry, including temperature dependencies of the biological tissue and the synthetic vivianite. Mössbauer spectrometry was chosen as the main investigation tool for identification of Fe2+ and Fe3+. We are identified divalent and trivalent iron in the samples and we found their mutual ratio. The iron sandwich complexes exhibit a linear dependence between quadrupole splitting and number of methyl groups. We also determined temperature of transformation of divalent to trivalent iron for vivianite sample that are used in painting. The transformation temperature is about 90°C. |
