In this research, iron-dextrin complex has been successfully synthesized from ferric chloride and dextrin in aqueous solution. The complex powder was thoroughly characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared (FT-IR), energy dispersive X-ray spectroscopy (EDX), and thermal analysis (DTA-TGA). The results indicated that the complex contains akaganeite (beta-FeOOH) core bounded by dextrin molecules. The akaganeite core ranges from 20 to 30 nm and the complex grain size varies from 40 to 60 nm. EDX analysis showed that the percentage of iron in the product nearly 25 percent by mass.
