In the present study the chemical modification of Ficus carica bast fiber with acrylic acid using ceric ammonium nitrate and nitric acid was done in aqueous medium. The raw and modified fibers were characterized using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and X-ray diffraction (XRD). The raw and modified samples were evaluated for swelling behavior in water and chloroform. The chemical resistance was investigated against 0.1N HCl and 0.1N NaOH. The chemically modified Ficus carica fiber (CMBF) showed morphological transformations, thermal stability and chemical resistance. The adsorption potential of modified fiber was investigated for Cr(VI) removal from aqueous system. Copyright © 2013 VBRI press.
