Synthesis of Chitosan-Coated Magnetic Microparticle Using Glutaraldehyde as Crosslinker and PEG as Spacer Arm and Its Application as Adsorbent of Peat Humic Acid

A simple procedure for synthesis of chitosan-coated magnetic microparticles (CMMP) using glutaraldehyde as a cross-linker and polyethylene glycol (PEG) as a spacer arm has been developed. The functionalized microparticles were prepared using an inexpensive, simple, rapid, one-pot process, based on t...

Summary:A simple procedure for synthesis of chitosan-coated magnetic microparticles (CMMP) using glutaraldehyde as a cross-linker and polyethylene glycol (PEG) as a spacer arm has been developed. The functionalized microparticles were prepared using an inexpensive, simple, rapid, one-pot process, based on the heating of chitosan, PEG, and ferrous sulfate mixture at high pH. X-ray diffraction results indicated that the surface-modified Fe3O4 microparticles did not lead to phase change unlike the pure Fe3O4. Magnetic chitosan adsorbent has been evaluated for removal of peat humic acid from its aqueous solution.
