Abstract

Micron-sized SUPER-PARAMAGNETIC polyglycidyl methacrylate (PGMA) particles with imidazole groups were prepared by a process involving: (1) magnetic Fe3O4, obtained by chemical coprecipitation of iron (II) and iron (III) salts in ammonium hydroxide in presence of oleic acid, (2) magnetic micron-sized PGMA based latex particles, prepared by DISPERSION POLYMERIZATION of polyglycidyl methacrylate in toluene and ethanol in presence of NANO FE3O4, and (3) functional groups of imidazole, introduced by chemical modification of the PGMA particles with imidazole. The resultant magnetic PGMA particles with imidazole groups were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscope (TEM), vibrating sample magnetometry, and elemental analysis. The existence of imidazole groups and its structure were confirmed by FTIR. The average diameter of magnetic chelating resin was 5.3 mm and the coreshell structure was confirmed by TEM. The chelating resin retained super-paramagnetism. The static adsorptions of Hg2+, Cd2+, Cu2+, Pb2+, Zn2+, Mg2+, and Co2+ were investigated and the adsorption capacities were calculated. The resin can absorb Cd2+ and Hg2+ and show effective adsorption of Cu2+. The highest capacity value of Cu2+ was obtained to be 3.606 mmol/g.
