Preparation and Properties of Environmentally Friendly Water Treatment Material

A new kind of water treatment composite was prepared by melt blend for diesel oil and chromium (VI) absorption, Ethylene Propylene Diene Monomer (EPDM) was the matrix, calcinatory Fe₂O₃ and anion exchange resin were the fillers. This composite can suspend in water-oil contact. The results showed that the diesel oil absorbencies were step-down and chromium (VI) absorbencies increased continuously as anion exchange resin loadings from 1% to 7%. The composite can adsorb diesel oil and chromium (VI) simultaneously. The optimized proportion of calcinatory Fe₂O₃ and anion exchange resin in composite was 17/3. This composite was a low cost and convenient new material for waste water treatment.
