Abstract | Removing phosphate ions from eutrophic waters is of paramount importance; however, the design of low-cost, high-performance adsorbents for phosphorus removal has remained a huge challenge. Herein, we have demonstrated the fabrication of a low-cost, eco-friendly absorbent, LPC@La(OH)3, by loading lanthanum hydroxide nanorods within lignin-derived porous carbon for superfast and highly efficient phosphorus removal. As-prepared LPC@ La(OH)3 exhibits a high adsorption capacity of 60.24 mg PL−1 and a high lanthanum usage efficiency. Our results show an ultrafast removal of up to 99.5% phosphate in 10 min when the initial concentration is 2 mg P L−1. Moreover, LPC@La(OH)3 can efficiently reduce the phosphate concentration to meet the below U.S. Environmental Protection Agency limits (50 μgPL−1) for eutrophication prevention. More importantly, it shows a high phosphate absorption ability over the wide range of pH 3−7, in addition to a high adsorption selectivity toward phosphate and high stability during adsorption process. Both the chemical precipitation and the ligand exchange are mainly responsible for the phosphate removal by LPC@La(OH)3. As-designed lignin-derived, ecofriendly, high-performance LPC@ La(OH)3 shows enormous potential for the phosphate removal from both municipal wastewater and industrial effluents. |
