| Abstract | ||||
| JUTE FIBERS were grafted with acrylonitrile (AN) induced by direct gamma irradiation. All the factors which affect the grafting process were investigated. The grafting at the optimum conditions was followed by amidoximation reaction. The conversion of AN into acrylamidoxime was studied by fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The treated Jute fibres were used as an adsorbent substrate for heavy metal ions such as Pb2+, Cu2+, Ni2+ and Fe2+ from their solutions. The different factors which affect the adsorption capacity of heavy metal ions, such as pH, contact time, metal ions concentrations were studied and the Langmuir adsorption isotherm was highlighted. It was found that the adsorption capacity was enhanced at acidic medium of pH 4 and increased with increasing of contact time. | ||||
