The research paper focuses on preparing a nanoadsorbent derived from Moringa oleifera seed pods. This nanoadsorbent was modified using orthophosphoric acid (H3PO4) and used as an adsorbent for removing Methylene blue (MB) dye from aqueous solutions. Characterization of the AC-MO (Activated carbon of Moringa oleifera) nanoadsorbent was conducted using Scanning Electron Microscopy (SEM), Fourier Transform Infrared Spectroscopy (FTIR), and X-ray Diffraction (XRD) techniques to analyze its structure and properties. In the batch process, various operational parameters such as contact time, initial dye concentration, adsorbent dosage, and pH were studied to determine their impact on the adsorption process. The results indicated that the highest adsorption of methylene blue occurred at pH 7, reaching equilibrium within 90 minutes at an initial MB concentration of 100 mg/L, with an adsorbent dosage of 20 mg/50 mL for each sample. The removal efficiency of MB dye increased with higher pH levels, and pH 7 exhibited the maximum removal capacity for all samples. The adsorption data were analyzed using Langmuir and Freundlich isotherm models, with the Langmuir isotherm model showing the best fit, suggesting maximum monolayer adsorption. Moreover, the pseudo-second-order kinetic model provided the best correlation for the experimental data. Overall, the AC-MO nanoadsorbent proved an effective adsorbent for removing MB dye from aqueous solutions, demonstrating its potential application in water treatment and environmental remediation processes.
