polyethylenimine

Application of SD/MNP/PEI Nanocomposite for Heavy Metals Sorption

 magnetical nanocomposite based on sawdust, magnetic nanoparticles, and polyethylenimine was prepared to remove Pb(II), Cd(II) and Cu(II) ions from an aqueous solution. Adsorption on nanocomposite exhibited a maximum removal of 97% for Pb(II)‏. The adsorption capacity in the pseudo-second-order model for Pb(II) was studied and the value of 1.48 mg/g was obtained.
