Abstract
Fe-gluconate was studied by means of the Mössbauer spectroscopy in the temperature interval of 80–305K. The measured spectra were analyzed in terms of two components (subspectra) and, alternatively, two distributions of the quadrupole splitting. The major component (~85%) was identified as due to high-spin Fe2+ ions, while the identification of the minor component (~15%) was not unique: some characteristics are in favor of the high-spin Fe3+ state, while other ones are consistent with the low-spin Fe2+ state. Values of the Debye temperature were determined for both components from a temperature dependence of the center shift as well as from that of the spectral area, but they are not conclusive as far as the unique identification of the ionic states of Fe in the components is concerned. The force constant for the high-spin ferrous atoms was evaluated to be equal to 44N m−1 (243 cm−1).
