Abstrakt: | Determination of the iron state (Fe2+ or Fe3+) and content of iron in commercial pharmaceutical products containing ferrous fumarate FeC4H2O4 was made by the Mössbauer spectroscopy and X-ray fluorescence method. Also, influence of thermal treatment on stability of ferrous fumarate in selected medicaments has been investigated. The investigated samples were annealed in definite temperature: 373, 473, and 573 K for 5 h. Room temperature Mössbauer spectra of initial samples gave clear evidence that two phases of iron were presented. The major component was connected with ferrous fumarate with a contribution from 85% to 50%, depending on investigated medicaments. Ferrous fumarate was stable up to annealing temperature 473 K. Above this temperature significant oxidation of Fe2+ to Fe3+ was observed. |
