Lignocellulosic biomass (LB) is a good choice to be utilized as a substitute for activated carbon (AC) production. The main objective is to increase pore volume, porosity, and specific surface area (SSA) of activated Gleditsia triacanthos (AGT) and determine the relevant mechanism behind pore formation. Morphological, physical, and chemical characteristics were studied to evaluate the potential of AGT for Ni²⁺ removal. Ni²⁺ removal was carried out for different operating conditions such as contact time, pH, and initial Ni²⁺ concentration. Kinetics and equilibrium studies demonstrated that the mechanism for Ni²⁺ removal is chemical sorption.
