Adsorption of Heavy Metal Ions with Magnetic Carbon-Coated Iron Nanoparitcles

Abstract:

Magnetic carbon-coated iron nanoparitcles were employed as adsorbent to study the adsorption characteristics of some metal ions, such as Cr, Ni, Cu, Pb, Zn. The effect of solution conditions such as pH, amounts of adsorbent, the co-existent ions was investigated. The results show that adsorption property of carbon-coated iron particles to heavy metal ions is improved at the condition of treated by H2O2, and at pH 8-9.5, Cr、Ni、Cu、Pb and Zn were retained on 30mg carbon-coated iron nanoparticles after shaking 3 min, and could be eluted by acid solutions(pH=1~2).
