High-affinity phosphate capture on MgO/Mg(OH) 2 -decorated wattle bark biochar: adsorption mechanism and regeneration performance

Year: 2026

Type: article

Abstract: did not shift after adsorption, indicating that the immobilization of phosphate was mainly due to inner-sphere complexation and poorly crystalline surface precipitation and not to bulk phase transformation. The initial phosphate removal efficiency of MgO-BC was found to be over 80% after five adsorption-desorption cycles, which confirms good regeneration potential. Based on these results, MgO-BC could be identified as an effective and reusable phosphate removal and recovery sorbent from aqueous systems.
