Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate),
poly(GMA-co-EGDMA), with different porosity parameters were synthesized by suspension copolymerization and
modified by ring-opening reaction of the pendant epoxy groups with ethylene diamine (EDA). The samples were
characterized by mercury porosimetry, FT-IR spectroscopy and elemental analysis. The sorption rate of the modified
copolymer, poly(GMA-co-EGDMA)-en for Cu(II) ions determined under non-competitive conditions was relatively
rapid, i.e. the maximum capacity was reached within 30 min. Batch sorption capacities for Cu(II), Fe(II), Mn(II),
Cd(II), Zn(II), Pb(II), Cr(III) and Pt(IV) ions were determined under non-competitive conditions in the pH range 1.25–
5.5 at room temperature. The maximum sorption capacities of poly(GMA-co-EGDMA)-en under non-competitive
conditions were 1.30 mmol/g for Pt(IV) at pH 5.5, 1.10 mmol/g for Cu(II) at pH 5.5, 1.06 mmol/g for Pb(II) at pH 1....25
and 0.67 mmol/g for Cd(II) ions at pH 5.5. The selectivity of poly(GMA-co-EGDMA)-en towards Cu(II), Co(II),
Ni(II), Pb(II) and Pt(IV) ions was investigated under competitive conditions. Poly(GMA-co-EGDMA)-en showed high
selectivity for Pt(IV) over Cu(II), Co(II), Ni(II) and Pb(II) ions at pH 2.1. At pH 5.5, the metal sorption capacities of
poly(GMA-co-EGDMA)-en decreased in the order: Cu(II)>Co(II)>Pt(IV)_Ni(II)>Pb(II). Regeneration of the
Cu(II), Ni(II) and Pb(II) loaded poly(GMA-co-EGDMA)-en with 2 M H2SO4 showed that the polymer can be reused
in several sorption/desorption cycles.
