Summary: Chitosan crosslinked with potassium tripolyphosphate (CTPP) and monochlomacetic-acid-modified chitosan crosslinked with potassium tripolyphosphate (MCTPP) were synthesized for efficient removal of UO22+ from acidic radioactive effluents. The adsorption process was influenced by factors such as pH and adsorbent dose, and the adsorption mechanism was found to be an endothermic single-layer process. The synthesized composites showed high adsorption capacities for UO22+ and were minimally affected by common metal ions.
