Phosphorus Removal from Wastewater Using a Novel Adsorbent: A Study on the Adsorption Capacity and Mechanism

• The novel adsorbent achieved a maximum phosphate adsorption capacity of 45.2 mg/g, outperforming many conventional adsorbents. • Adsorption kinetics followed pseudo-second-order model, and equilibrium data fitted Langmuir isotherm, indicating monolayer chemisorption. • The adsorbent exhibited excellent regeneration capability, retaining over 80% removal efficiency after five cycles, making it cost-effective. • Thermodynamic analysis revealed spontaneous and endothermic adsorption, suggesting potential for industrial application in wastewater treatment.
