Preliminary tests demonstrate high removal efficacy, suggesting that this adsorbent is a strong candidate for further research. Figure 6 – Results of the batch tests using MOS to remove uranium. 4. DISCUSSION Moringa Oleifera seeds exhibit high uranium adsorption capacity and are abundant and inexpensive. The comparative evaluation of (MOS) and unmodified Chitosan reveals distinct performance disparities in the removal of uranium from aqueous effluents. While the literature often highlights Chitosan as a viable adsorbent, this study confirms substantial operational limitations in its unmodified form. Additionally, the extracted material formed a viscous slurry upon mixing, impeding mass transfer and filtration and limiting uranium removal to approximately
