摘要:
Reaction of the cationic ion exchange resin Dowex 650C with an excess of aqueous ferric chloride yields a material that, upon pyrolysis, is converted to porous, spherical, nanocrystalline hematite particles (average crystallite size 12.0 nm). The resulting iron oxide has a low density (2.4 g cm(-3)) and a relatively high surface area (30 m(2) g-1), and serves as a good sorbent for arsenic.
