- Abstract
A novel N-succinyl-O-carboxymethyl chitosan (NSOC) was synthesized by a simple two-step method. O-carboxymethyl chitosan (OCMC) was prepared first by reacting chitosan with chloroacetic acid, and then the achieved OCMC was further succinylated by succinic anhydride in aqueous solution. The resultant NSOC was characterized by Fourier transform infrared (FTIR), elemental, 1 H nuclear mag)netic resonance (1 H-NMR), scanning electron microscope (SEM) and X-ray diffraction pattern (XRD) analysis. The adsorption of Pb(II) was subsequently investigated. The adsorption isotherms obeyed the Langmuir equation, and the adsorption kinetics followed a pseudo-second-order model. FTIR and X-ray photoelectron spectra results showed that the excellent adsorption performance of NSOC for lead ions was attributed to the presence of large number of carboxyl groups.
