Synergistic remediation of aqueous Cd( ii ) by sewage sludge biochar via P/Fe co-impregnation
Abstract
). Approximately 90% of the removal amount remained after five adsorption-desorption cycle, indicating high stability and strong regeneration potential. Mechanistic analyses indicated a synergistic removal network involving electrostatic attraction, chemical precipitation, inner-sphere surface complexation, cation-π interaction, and ion exchange. P-Fe@SBC represented a promising waste-derived material for "waste-to-treat-waste" remediation.
