20080221248 | METHOD FOR PREPARING SURFACE-IMPRINTED POLYMER MICROSPHERES IN THE FORM OF CORE-SHELL FOR SELECTIVE SEPARATION OF HEAVY METAL IONS - Disclosed is the preparation of a molecularly imprinted polymer for the selective separation of heavy metal ions using a core-shell polymerization method. According to the core-shell polymerization method, the molecularly imprinted polymer is prepared through two steps of preparing seed particles using styrene and divinylbenzene and forming a metal ion imprinted polymer on the surface of the seed particles. In the imprinted polymer thus prepared, an imprinted site is present on the surface of a support (e.g., polystyrene beads), thus reducing the time required to recognize heavy metal ions and obviating the use of a surfactant or a stabilizer, thereby realizing economic and environmental advantages. | 09-11-2008 |
