Jute fibers were grafted with acrylic acid by using the direct gamma irradiation technique, which used as an adsorbent substrate for the toxic heavy metal ions such as Hg 2+ and Pb 2+ from their aqueous solutions. The structure and crystallinity of the grafted jute fibers were characterized by using Fourier‐transform infrared spectroscopy and X‐ray diffraction, respectively. The effect of pH range of the metal ion solutions, contact time, and the adsorption kinetics of the adsorption process were investigated. The effect of the initial concentration of dissolved metal ions and the adsorption isotherm for both Langmuir and Freundlich adsorption models were also investigated. From the results, it can be concluded that the adsorption process obeys the second‐order kinetic reaction and follows the Langmuir adsorption isotherm model, while, about 86 and 80% of Pb 2+ and Hg 2+ , respectively, were adsorbed at pH 5 and 6 after a contact time of 60 min.
