摘要
The synthesis and adsorption capacity of carbon nanotubes (CNTs)-iron oxides magnetic composites were investigated. The sample composites exhibited good adsorption capacity for Pb(II) and Cu(II) from aqueous solution. The magnetic composites were synthesized from a suspension of 1.0 g oxidized CNTs in a 300 ml solution of 0.585 g FeCl3 · 6H2O and 0.390 g FeSO4 · 6H2O. at 70 °C under N 2 atmosphere. The powder XRD characterization of the sample composites showed that the magnetic phase formed was maghemite or magnetite. The adsorption of the sample composites was found to be pH dependent.
