Carbon-Coated Multifunctional Magnetic Nanoparticles for Fluorescent Detection and Removal of β‑Lactam Antibiotics from Water.

ABSTRACT: The present study addresses the design of an innovative magneto-luminescent nanocomposite by coating cobalt ferrite nanoparticles with an organic layer, enhancing their multifunctional properties. Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy (Raman), and X-ray photoelectron spectroscopy (XPS) analyses confirm the successful formation of an organic layer rich in functional groups, including hydroxyls, carbonyls, and amines. These groups influenced the surface charge, resulting in positive ζ-potential at acidic pHs and negative ζ-potential at alkaline ones. Nitrogen adsorption measurements and Brunauer-Emmet-Teller (BET) and Barrett-Joyner-Halenda (BJH) analyses revealed a decrease in surface area but an increase in pore size and volume. The nanocomposite particles exhi
