Synthesis and Characterization of Magnetite-Pectin-Alginate Hybrid and Bionanocomposite

Abstract

It is a one pot synthesis of hybrid bionanocomposite comprising of inorganic magnetite with stabilizer biopolymer pectin and alginate in co-precipitation method using sodium hydroxide and ammonium hydroxide as precipitating agents. A lot of comparison and investigation has been done in particle size of nanocomposite by changing the stoichiometric ratio of both magnetite and biopolymer concentration and drying condition of composite. The nanocomposite has been characterized using infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray powder diffraction (XRD) and (UV-analyzer). SEM showed particle size of the nanocomposite and FTIR data confirmed the COO-Fe linkage between polymer COOH group and Fe3O4. Keywords: Alginate, Biopolymer, Nanocomposite, Pectin
