L-Lysine-Coated Magnetic Core-Shell Nanoparticles for the Removal of Acetylsalicylic Acid from Aqueous Solutions.

Nanotechnologies based on magnetic materials have been successfully used as efficient and reusable strategies to remove pharmaceutical residuals from water. This paper focuses on the fabrication, characterization, and application of ferrite-based magnetic nanoparticles functionalized with L-lysine as potential nanoadsorbents to remove acetylsalicylic acid (ASA) from water. The proposed nanomaterials are composed of highly magnetic and chemically stable core-shell nanoparticles covered with an adsorptive layer of L-lysine (CoFeO-γ-FeO-Lys).
