An environment friendly water-soluble carboxymethyl chitosan/carboxyl group of multi-walled carbon nanotubes (WSCC/MWCNTs-COOH) composite was prepared by using carboxyl group of multi-walled carbon nanotubes (MWCNTs-COOH) and aqueous carboxymethyl chitosan (WSCC) solution. The WSCC/MWNTs-COOH composite was used as an adsorbent to adsorb Pb(II) in water via non-covalent adsorption interaction. In the batch adsorption experiments, the optimal adsorption conditions and maximum adsorption efficiency were determined by investigating the influence of adsorbent concentration, contact time and Pb(II) initial concentration, respectively. This study will provide a novel adsorbent for detection and removal of harmful Pb(II) residues in water.
