%X Magnetic microspheres were prepared through partial reduction-precipitation method. The surface of particles was modified by silane-coupling agents. The structure and properties of these magnetic microspheres were characterized by X-ray, TEM, AFM, IR, etc. The magnetic nanoparticles modified by silane- coupling agents present favorable dispersibility, responsibility to magnetism and resist against the corrosion of acid or alkali solution. The results of investigation on modified nanoparticles with different silane-coupling agents also indicate that the particles have multi functional organic groups on their surface, such as -OH, -NH_2, -NH, -C=O, -C=C.
