iron iodate is an inorganic compound formed by the covalent bonding of one iron and two iodine atoms. It is hygroscopic and sensitive to light. It has a broad range of scientific research applications, including acting as a catalyst for organic reactions, oxidizing dyes and pigments, and analyzing iron levels in biological samples.
We have investigated the mechanical properties of iron iodate nanocomposite dispersed on Al2O3 nanoparticles deposited on a DGEBA resin (bisphenol A diglycidyl ether + diethylene triamine). The results show an enhancement of Young’s modulus due to the presence of the iodate particles with a weak mass percentage percentage, and a shift in the glass transition temperature.
The morphology of the Fe(IO3)3 particles was analysed by SEM and TEM, revealing two kinds of shapes: needles with a diameter in the range of a few tens of nanometers and balls of 20-30 nm in size. X-ray powder and single crystal diffraction measurements showed that the particles retain the P63 phase of the single crystal, and this observation was confirmed by Intermittent-Contact Atomic Force Microscopy in the normal mode (IC-AFM).
In aqueous solution, Fe(IO3)3 forms an iodate ion with four fundamental vibrations: one at 779 cm-1, three at 395, 549 and 451 cm-1. It has been shown that iodate ions are unreactive with phenol in neutral medium, but they react with periodate in an excess of IO4- and with Fe(phen)32+ in the aqueous solution of ferrioin.
