Study on the N-O-Carboxymethyl Chitosan- Fe2+ Complex and its Adsorption of CO
N-O-carboxymethyl chitosan was used to adsorb Fe2+, which was indicated by FTIR And the Fe2+-eomplex was characterized by SEM and DTA. Results show that the microstructure and thermal stability of the complex is significantly different from that of N-O-carboxymethyl chitosan. The Fe2+-complex was used to adsorb CO, and its adsorption capacity reached the maximum of 1.75 mg-g-1 when the reaction was occurred at 40℃ for 6h and the granularity of the complex is 80 mash. The adsorbing capacity for CO of Fe2+-complex is up to 4 times higher than that of chitosan and N,O-CMC, and the adsorbing capacity ofCMC-Fe2+ is higher than that of CTS-Fe2+.
