Abstract

Iron oxide nanoparticles were produced by a green synthetic route using an extract of Syzygium cumini leaves (bINP) and employed as a Fenton like catalyst for degradation of Reactive Red 238 (RR238) and Reactive Blue 235 (RB235), dye mix and wastewater collected from the textile dyeing industry. The synthesized nanoparticles were characterized by Fourier Transform Infra Red (FTIR) Spectroscopy, Scanning Electron Microscopy/ Energy Dispersive X-ray (SEM/ EDX) Analysis, Transmission Electron Microscopy (TEM) and X-ray Diffractometry (XRD). The decolorization efficiency of bINP was compared with iron oxide nanoparticles produced by borohydride reduction (cINP), using UV-visible spectroscopy. The degradation efficiency of bINP (2.0 gl^-1) towards RR238 and RB235 was found to be 100% and that of cINP was found to be 70% and 71%, respectively.
