Preparation of magnetic starchy composite microspheres and its characteristics |
| |
| Abstract: | The magnetic starchy composite microspheres was prepared, containing magnetite cores surrounded by chemisorbed starch ,50-370?nm in diameter, distributed uniformly. They have good magnetic responsibility in the presence of magnetic field and good dispersion stability in water. The optimum preparation condition is as follows: mass concentration of starch and ferrous are 124.95?mg/mL and 53.00?mg/mL respectively, pH value of solution is higher than 9.73. |
