Abstract
Hazardous organic chemicals, like phenol found in wastewater, frequently cause serious health issues for living things, including people. Therefore, this study concentrates on creating and applying iron-doped titanium dioxide in coated forms for the photocatalytic degradation of phenol by irradiating it with UV and visible light. Fe-doped TiO2 nanoparticles were created using a simple and efficient technique. Energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM) and Fourier Transform infrared (FTIR) analysis were applied to identify the prepared photocatalyst. Different operational parameters, like wastewater pH (3, 6, 7 and 9), initial concentration of phenol (3, 6, 9 and 10 ppm), weight percent of Fe onto catalyst (0, 1.20 and 2.60 wt%) and light intensity of 8 W lamp for UV light and 36 and 72 W lamp for visible light have been studied to see how they affect phenol degradation. The results showed that the removal rate of phenol decreases with an increase in the initial concentration and pH of the solution. The decomposition of phenol of 93.17% was accomplished in a 120 min of the operation period by working at pH 3, initial concentration of phenol 3 ppm and Fe loading percent of 2.60 wt%. At the same conditions, degradation of 80.53% was obtained using Fe-TiO2 irradiated by visible light. Based on the results, the Fe-doped TiO2 nanoparticles have more effective phenol photodegradation than undoped TiO2.
