- Abstract
- We synthesized the self-organized nanoporous oxide with potentiostatic anodization of iron foil. The iron oxide nanocomposite (INCs) were fabricated in 1M Na2SO4 containing 0.5wt% NaF electrolyte holding the potential at 20, 40 and 60 V for 20min, respectively. Field Emmision Scanning Electron Microscopy (FESEM) and X-ray Diffractometer (XRD) were used to evaluate the micromorphology and crystalline structure of INC film. Also, this study was performed to evaluate the fenton reaction using INC film with hydroperoxide for degradation of cyanide dissolved in water. In case of INC-40V in the presence of H2O2 3%, the first-order rate constant was found to be 1.7 × 10-2 min-1, and indicated to be 1.2 × 10-2 min-1 on commercial hematite powder. This result is shown to be good performance enough to replace the powder type for treatment of wastewater.
