Synthesis and characterization of Fe⁰@chitosan/cellulose biocompatible composites from natural resources as advanced carriers for ibuprofen drug: reaction kinetics and equilibrium

Fe 0 @chitosan/cellulose was synthesized as a carrier for Ibuprofen drug. It has achieved a loading capacity of 553 mg g −1 and a slow release profile for 260 h, which is controlled by complex diffusion and erosion mechanisms.
