Synthesis and Applications of a Novel Copolymer of Chitosan as Heavy Metal Removal Agent

Abstract:

Article Preview

The graft copolymer, chitosan-g-AM-AA, was prepared through graft polymerization of acryamide and acryl acid onto chitosan by K2S2O8 initiation under homogeneous conditions in 2 wt% acetic acid. The product was characterized by infrared spectrometry (IR), differential scanning calorimetry (DSC) and scanning electron microscopy (SEM). The adsorption capacities and removal ratioes of the copolymer for heavy metal ions were studied by using medium concentration (about 50mg/L) of Cu2+ ,Zn 2+and Pb2+ at pH 6. The results indicated the copolymer exhibited higher adsorbability than chitosan.
