Abstract: A new kind of material for oil and Cr(Ⅵ) absorption was prepared by melt blend, with ethylene propylene diene monomer(EPDM) as the matrix and calcinatory Fe2O3 and anion exchange resin 201Х7 as the fillers. The composites can suspend in water-oil contact(WOC). The absorbencies of composites for water and oil changed greatly with various ratios of calcinatory Fe2O3 and anion exchange resin 201Х7. The results show that the absorbency of oil into the composite increased continuously while that of Cr(Ⅵ) was step-up with anion exchange resin loadings from 1% to 7%. The optimized ratio of calcinatory Fe2O3 and anion exchange resin 201Х7 was got when the absorbencies of composites for oil and Cr(Ⅵ) reached maximum simultaneously. The total adsorptive capacities of both oil and Cr(Ⅵ) were much higher than those of oil or Cr in one adsorption medium.
