Abstract

Abstract Monodispersed Fe3O4 magnetic particles adsorbed by amylase (such as citric acid (CA), carboxymethyl chitosan (CMCH) and β-cyclodextrin (CD)) were prepared by means of co-precipitation method. The absorption character of the samples was investigated by FT-IR, TG and VSM. It was found that the carboxyl (COOH groups) of amylase reacted with the hydroxyl (OH groups) on the surface of Fe3O4 particles, resulting in the formation of iron carboxylate that was adsorbed onto Fe3O4. The induction heating properties of the magnetic Fe3O4 nanoparticles in an alternating current magnetic field were also investigated and the thermo-magnetic stability in induction heating was discussed.
