Bio-Polymer Based Tragacanth Gum (TG) Loaded Fe3O4 Nanocomposite for the Sequestration of Tenacious Congo Red Dye from Waste Water

March 27, 2020


Water polluted by hazardousdyes such as congo red (CR) face challenges to the regulation of water supplies. In the laboratory scale experiment, we report the novel approach for the synthesis of Fe3O4/TG nanocomposite. The Fe3O4/TG nanocomposite was synthesized by co-precipitation method. The surface properties and chemical compositions have been investigated using Fourier transform infrared spectroscopy (FTIR), X- ray diffractometer (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) instrumentation. The XRD study indicates that nanocomposite were formed in the nano-scale (11.5 nm) and this is in accordance with TEM results. The maximum removal of CR dye was recorded at 2.0 pH. Approximately, 89.51 % deterioration of congo red (CR) dye has been achieved within 250 min of solar exposure. The prepared Fe3O4/TG nanocomposite is found to efficient photocatalyst for the removal of noxious dye from waste water.
