The　monodisperse　cross-linked　PS-DVB-GMA-amino-Fe3O4　magnetic　microspheres　with　functional　group　of　amino　were　synthase　by　seed　swelling　method　using　PS　microspheres　as　seeds,　and　glycidyl　acrylate　as　monomer　in　the　swelling　polymerization;　and　then　modified　poly　(styrene-glycidyl　methacrylate)　(PS-DVB-GMA)　microspheres　with　ethylene　diamine　to　form　amino-groups;　subsequently,　Fe3O4　nanoparticles　were　grafted　on　the　microspheres　through　in　situ　precipitation　reaction.　The　morphology,　composition,　magnetic　properties,　and　crystalline　structure　of　the　magnetic　microspheres　were　characterized　by　scanning　electron　microscope　with　energy　dispersive　analysis　of　X-rays　(SEM/EDX),　transmission　electron　microscopy(TEM),　vibrating　sample　magnetometer(VSM),　X-ray　diffraction(XRD),　Fourier　transform　infrared　spectroscopy　(FTIR)　and　thermogravimetric　analysis　(TGA)　methods,　respectively.　The　resulting　PS-DVB-GMA-amino-Fe3O4　magnetic　microspheres　were　tested　for　their　ability　to　remove　copper　(II)　ions　from　an　aqueous　solution　in　batch　experiments.　The　effects　of　adsorption　time　and　pH　value　on　the　adsorbed　dosage　of　copper　ions　on　magnetic　microspheres　was　investigated.　Besides,　two　adsorption　isotherm　models　(i.e.,　the　Langmuir　and　the　Freundlich　models)　were　used　to　fit　the　experimental　isotherm　adsorption　data.　The　average　size　of　microspheres　was　5.92　mu　m　with　the　PDI　was　0.024.　The　composite　magnetic　microspheres　could　be　easily　separated　from　solution　by　magnetic　decantation　using　a　permanent　magnet.　The　adsorption　experiments　demonstrate　that　copper　ions　adsorption　onto　the　PS-DVB-GMA-amino-Fe3O4　magnetic　microspheres　reaches　a　maximum　after　the　45　min.　The　maximum　adsorption　capacities　(q　(e)　=　76.8　mg/g)　was　reached　at　the　pH　value　of　5.0　when　the　temperature　was　25　A　degrees　C,　and　by　simulating　the　experimental　data　with　the　Langmuir,　the　maximum　equilibrium　absorption　capacity　of　PS-DVB-GMA-amino-Fe3O4　magnetic　microspheres　was　134.0216　mg/g,　showing　a　good　adsorptive　property　to　Cu　(II).
