Preparation of Novel Magnetic Fluorescent Microspheres Obtained by Chemical Method

摘要

The aim of this study is to analyze the properties of microspheres, which was obtained from an iron tailings. The flow-sheet of chemical method consists of chemical co-precipitation of Fe_3O_4 magnetic microspheres, SiO_2 packaged and amino silicon alkylation modification with anthrone under NaBH_4 existence. The results show that microspheres can be obtained successfully and it not only has a strong magnetism, but also has a fluorescence effort with the irradiating processing by ultraviolet with a wavelength of 282nm. This microsphere particle is a kind of high-value, environmentally-friendly products, it can be traced and served as a magnetic guide due to its magnetism and fluorescence properties, which has a big potential in medical technology and biological science.
