Cerium oxide nanoparticle functionalized lignin as a nano-biosorbent for efficient phosphate removal
Removing excess phosphorus is a highly effective method to prevent eutrophication in contaminated water. However, the design and preparation of an efficient biosorbent for phosphate capture is still a great challenge. We fabricated a novel, and inexpensive nano-biosorbent, L-NH(2)@Ce, by loading cer...

description | Removing excess phosphorus is a highly effective method to prevent eutrophication in contaminated water. However, the design and preparation of an efficient biosorbent for phosphate capture is still a great challenge. We fabricated a novel, and inexpensive nano-biosorbent, L-NH(2)@Ce, by loading cerium oxide nanoparticles (nano-CeO(2)) within the aminated lignin using a facile in situ precipitation approach for efficient phosphate removal. The as-designed nano-biosorbent L-NH(2)@Ce exhibited a BET surface area (S(BET)) of 89.8 m(2) g(−1), 3 times that of lignin, and a pore volume (V(p)) of 0.23 cm(3) g(−1). Owing to these results, the adsorption capacity of L-NH(2)@Ce increased by 14-fold to 27.86 mg g(−1) compared with lignin (1.92 mg g(−1)). Moreover, the L-NH(2)@Ce can quickly reduce a high phosphate concentration of 10 ppm to well below the discharge standard of 0.5 ppm recommended by the World Health Organization (WHO) for drinking water. Importantly, a study of leaching tests indicated the negligible risk of Ce ion leakage during phosphate adsorption over the wide pH range of 4–9. Moreover, L-NH(2)@Ce exhibits good reusability and retains 90% of removal efficiency after two adsorption–desorption cycles. The environmentally benignity of the raw material, the simple preparation process, and the high stability and reusability makes L-NH(2)@Ce a promising nano-biosorbent for phosphate removal. |
