Sorption Properties of Fullerene-Modified Polystyrene

摘要

Polystyrene is modified with fullerene, and composite films are obtained. The kinetics of sorption of heavy metal ions from aqueous electrolyte solutions on the initial and modified polystyrene films is studied. The efficiency of sorption of copper ions of the modified polymer is found to be four times higher than on the unmodified samples. The selectivity of sorption on the composite can be presented with the following order: Cu(II) > Cd(II) > Ni(II) > Zn(II). The interaction between polystyrene and fullerene is studied by IR spec-troscopy.
