| Abstract: | The thermal decomposition of iron(III) succinate, Fe2(C4H4O4)2(OH)2 and iron(III) adipate pentahydrate, Fe2(C6H8O4)3·5 H2O, has been investigated at different temperatures for different time intervals in static air atmosphere using Mössbauer spectroscopy and nonisothermal techniques (DTG-DTA-TG). The reduction of iron(III) to iron(II) species has been observed at 533 K and 563 K in the case of iron(III) succinate and iron(III) adipate, respectively. At higher temperatures, α-Fe2O3 is formed as the final thermolysis product. |
