Degradation of Amido Black Dye Using Ultra-Violet Light Catalyzed by Iron Oxide Nanoparticles: Kinetics and Mechanism of Degradation
نویسندگان
چکیده
In this study, we investigated the degradation of amido black dye in an aqueous solution using ultra-violet (UV) light catalyzed by iron oxide nanoparticles (nano-Fe). The nano-Fe was synthesized sodium borohydride reduction ferric chloride and characterized scanning electron microscopy (SEM), X-ray diffraction (XRD), fluorescence spectrophotometry (XRF). SEM showed regular spherical particles, XRD examination a weak broad peak at Fe (1 1 0), XRF study that element with highest composition Fe2O3 (60.80%). experiments UV could effectively degrade dye. nano-Fe/UV system 5 mg/L up to 93.2% 254 nm after being irradiated for 60 min. be described Langmuir–Hinshelwood kinetic model, rate constants (kapp) were 0.0183–0.0323 min−1. Thus, combined can applied efficient remediation wastewater.
