Abstract: This study investigates the efficacy of Moringa oleifera seeds biomass in removing cadmium (Cd) from contaminated water. The biomass was characterized using scanning electron microscopy, infrared spectroscopy, and point of zero charge techniques. Adsorption experiments were conducted with varying adsorbent dosages (2 mg - 10 mg), pH conditions (4.5, 5.5, 6.5, 7.5, and 8.5), and contact times (ranging from 40 to 200 minutes) to assess the impact of these parameters on Cd removal. Optimal conditions for adsorption were identified as 10 mg of adsorbent at pH 8.5 with a contact time of 200 minutes. The M-Langmuir model was employed to linearize the adsorption isotherms, revealing a superior fit for Cd adsorption. The model suggested a multilayer adsorption process with a chemical nature characterized by an Amino mechanism. The maximum adsorption capacity (Q max) of the Moringa oleifera seeds biomass was determined to be 9.66 mg g−1, indicating a robust interaction with the metal. In conclusion, this study demonstrates the effectiveness of Moringa oleifera seeds biomass as a bio-sorbent for the adsorption of Cadmium from contaminated water. The findings suggest its potential as a viable alternative material for water purification and treatment, offering valuable insights into the adsorption process and mechanisms involved.
