IR spectrum of the materials showed the appearance of carboxyl groups on oxidized materials which enhances ion adsorption capacity for metals. Modified jute and coir was choiced to study the influential parameters such as initial metal ion concentration, contact time and pH of the solution on the adsorption process. The experimental data was well fitted by the pseudo-second-order kinetics model and Langmuir isotherm model. This study showed that under optimum conditions (pH = 5 and contact time of Ni and Pb experiment chosen at 30 and 120 minutes, repectively), modified coir had the highest potential of removal for metal ions, with maximum adsorption capacities were 48.54 mg/g and 19.34 mg/g for Pb(II) and Ni(II), respectively.}, issn = {2588-1094}, doi = {10.25073/2588-1094/vnuees.4166}, url = {https://js.vnu.edu.vn/EES/article/view/4166} }
