Facile synthesis of novel 3D flower-like magnetic La@Fe/C composites from ilmenite for efficient phosphate removal from aqueous solution

Abstract

In this study, a novel 3D flower-like La@Fe/C magnetic composite was successfully synthesized by carbothermal reduction of ilmenite via microwave radiation.

Phosphate removal and recovery by lanthanum-based adsorbents: A review for current advances

“…Liu et al (2018) synthesized carbon-coated J o u r n a l P r e -p r o o f Fe3O4(MFC) by hydrothermal method and then modified it with lanthanum hydroxide to prepare MFC@La(OH)3 to adsorb phosphate. Similarly, Wang et al (2019a) used ilmenite and coconut shell activated carbon as raw materials to produce nZVI loaded particles under microwave radiation and then introduced lanthanum to produce a new magnetic three-dimensional flower-like substance La@Fe/C. The presence of activated carbon not only reduced the agglomeration of nZVI, but also effectively controlled its oxidation.…”
