Rapid decolorization and mineralization of congo red using Fe78Si9B13 amorphous alloy by photo fenton-like process
Abstract
In this work, a multifunctional and novel metallic glass with the nominal atomic percentage of Fe78Si9B13 exhibited advanced catalytic capability for degrading congo red (CR) dye. The Fe78Si9B13 metallic glass was firstly characterized by X-ray diffraction (XRD), UV-vis diffuse reflectance spectrophotometers (UV-vis DRS), scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDS). 100% dye degradation was achieved within 20 min using Fe78Si9B13 metallic glass under rational parameter control. The total organic carbon (TOC) removal was reached more than 80% within 60 min. Tertiary butanol was used for the investigation of the production of hydroxyl radicals (•OH), resulting in a sharp decrease of dye color removal. The optimum condition for CR degradation in this work was at pH 3.4, catalyst dosage 0.5 g/L, dye concentration 20 ppm, light intensity 7.7 μW/cm2, H2O2 concentration 1.0 mM. The findings in this work will open a new gate for the metallic glass in wastewater treatment.
