Cerium oxide nanoparticle functionalized lignin as a nano-biosorbent for efficient phosphate removal.

ABSTRACT: 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-NH₂@Ce, by loading cerium oxide nanoparticles (nano-CeO₂) within the aminated lignin using a facile in situ precipitation approach for efficient phosphate removal. The as-designed nano-biosorbent L-NH₂@Ce exhibited a BET surface area (S _BET) of 89.8 m² g^-1, 3 times that of lignin, and a pore volume (V _p) of 0.23 cm³ g^-1. Owing to these results, the adsorption capacity of L-NH₂@Ce increased
