Adsorption Behavior of Fe3O4/ Poly (Acrylate Methy Lester-co-Divinylbenzene) Microspheres Toward Metal Ions
The Fe3O4/(acrylate methyl ester-co-divinylbenzene) magnetic microspheres were prepared by suspension polymerization. The application of these microspheres as an adsorbent for metal ions adsorption was examined. The results showed that the diameter of the magnetic adsorbent was 35～55 μm and the amount of Fe3O4 was 18％. The adsorbent showed high efficiency for the removal of metal ions. The maximum adsorption capacity (qm) obtained by the Langmuir isotherm was 2.3 mmol/g for Hg2+, 2.2 mmol/g for Cu2+ and 1.1 mmol/g for Ni2+. The adsorption rate constant calculated by Lagergrent equation was 0.023 min-1 for Hg2+, 0.034 min-1 for Cu2+ and 0.036 min-1 for Ni2+. Regeneration of the adsorbent was achieved using 1 mol/L H2SO4.
