Sustainable magnesium doped nanofibrillated cellulose/bentonite composite for enhanced phosphate removal: process optimization and mechanistic insights
Abstract
), XRD, FTIR, FESEM, EDX and XPS confirmed the successful synthesis of composite and incorporation of Mg, which strengthened electrostatic interactions and promoted inner-sphere ligand exchange with phosphate ions. Alkaline-assisted desorption enabled up to 90% phosphate release, and the adsorbent retained over 75% of its initial capacity even after seven cycles, demonstrating excellent stability and recyclability for nutrient recovery. Beyond water treatment, the phosphate-laden composites improved soil water retention, highlighting their potential for sustainable agricultural applications. Overall, this work expands the functional versatility of cellulose-clay composites, offering an environmentally benign strategy for integrated wastewater remediation and resource recovery.
