摘　　要：Magnetically assisted chemical separation (MACS) is a new method that uses either micro-or nanomagnetic particles whose surface is modified with a functional material (an extractant) as carriersMagnetically assisted chemical separation （MACS） is a new method that uses either micro- or nano- magnetic particles whose surface is modified with a functional material （an extractant） as carriers to separate and concentrate radionuclide in magnetic field. This method combines the simple magnetic separation techniques with high selective ion extractant, and it will be a simple, low-cost, effective process for separation of radionuclides from contaminated water with almost no production of waste streams. In this work, the preparation of magnetic particles （ADB18C6/PMA-Fe3O4 microspheres） has been studied systematically.
