Research of Preparation Factors on Magnetic Cassava Starch Microspheres

Magnetic cassava starch microspheres have been prepared by means of the method of precipitation magnetization, cassava starch as raw material adsorbing or embedding Fe3O4, many influence factors on magnetic cassava starch iron rate such as pH, reaction time, stirring speed, ratio of Fe+3 to Fe+2, reaction temperature also investigated in this paper. On the base above research, we preliminary got the optimal conditions on the synthesis of magnetic cassava starch microspheres.
