A Recyclable Magnetic Aminated Lignin Supported Zr-La Dual-Metal Hydroxide for Rapid Separation and Highly Efficient Sequestration of Phosphate.

ABSTRACT: The application of lignin-based adsorbents in the efficient removal of phosphate from wastewater has attracted much attention and been intensively studied in recent years. However, most currently reported lignin-based adsorbents are difficult to recover and recycle. Herein, we have developed a recyclable, nanostructured bio-adsorbent, poly(ethyleneimine) (PEI)-modified lignin (LG) integrated with Fe₃O₄ and Zr-La dual-metal hydroxide (LG-NH₂@Fe₃O₄@Zr-La), by the Mannich reaction followed by the chemical coprecipitation method. Multilayer adsorption existed on the surface of LG-NH₂@Fe₃O₄@Zr-La based on the isotherm fitting curve, and its adsorption capacity reached 57.8 mg P g^-1, exhibiting a h
