This research delves deeper into evaluating the adsorption capacity, removal phosphate efficiency, and potential industrial-scale application of this material through a fixed-bed column. Laboratory-scale experiments were conducted to investigate the impact of various parameters, including bed height, pH, initial concentration, and flow rate on the breakthrough curve. Mathematical models were used to simulate the breakthrough behavior. The efficacy of the fixed-bed column will be evaluated according to the examined criteria, followed by an analysis of material reusability to determine its performance and potential for regeneration.
