The study investigates the enhanced biosorptive recovery of manganese ions (Mn2+) from low-grade ore leachate using NaOH activated Mangifera indica kernel biomass. The objective is to optimize the recovery process through kinetic, isotherm, and desorption studies. The methodology involves the preparation of the biomass and subsequent batch experiments to evaluate the biosorption capacity under varying conditions. Kinetic models were applied to analyze the adsorption process data, while isotherm models were employed to interpret the equilibrium data. Results showed that the NaOH treatment significantly improved the biosorption capacity of the Mangifera indica kernel biomass, achieving a maximum removal efficiency of Mn2+ at optimal pH and biomass concentration. The adsorption kinetics followed a pseudo-second-order model, indicating chemisorption, while the Freundlich isotherm model best represented the adsorption equilibrium data. Additionally, desorption studies suggested a favorable reuse potential of the biomass for manganese recovery. This research demonstrates the effectiveness of using agricultural waste for metal recovery, thereby contributing to sustainable waste management and resource recovery practices.
