Process-Intensified Pb(II) Removal from Complex Matrices Using an Ultrasound-Assisted Magnetic Fe3O4@γ-Chitosan–Gallic Acid Nanocomposite
A magnetically recoverable Fe3O4@γ-chitosan-gallic acid (Fe3O4@Chi-GA) nanocomposite was engineered as a sustainable bioadsorbent for Pb(II) removal from complex environmental and consumer matrices. The material was synthesized via sequential surface functionalization of Fe3O4 nanoparticles with γ-chitosan and gallic...
