- A simple procedure for synthesis of chitosan-coated magnetic microparticle (CMMP) using glutaraldehydeas a cross-linker and polyethylene glycol (PEG) as a spacer arm has been developed. The functionalizedmicroparticle were prepared using an inexpensive, simple, rapid, one-pot process, based on the heating ofchitosan, PEG, and ferrous sulfate mixture at high pH. X-ray diffraction results indicated that the surfacemodifiedFe3O4 microparticle did not lead to phase change unlike the pure Fe3O4. Magnetic chitosanadsorbent has been evaluated for removal of peat humic acid from its aqueous solution.
