eparation,Characterization and Antibacterial Activity of Thiourea-chitosan-copper(II) Complex

Thiourea-chitosan-copper(II) complex was prepared,characterized by FT-IR,UV-visible spectroscopy,XRD and TG-DTA.The antibacterial activities of chitosan,thiourea-chitosan and thiourea-chitosan-copper(II) complex against E.coli and S.aureus were investigated.Results showed that the antibacterial activity of thiourea-chitosan-copper(II) complex was obviously enhanced when compared with chitosan.
