| Abstract: | Cross-linked chitosan salicylaldehyde schiff base microspheres were firstly prepared with glutaraldehyde as crosslinking agent under microwave radiation. Structure of the product was characterized by infrared Spectra and thermogravimetric analysis. The adsorption capacities of the sample on some metal ions were investigated. The sample was also compared with that produced by the traditional water-bath heating method. The results showed that microwave radiation could markedly enhance the rate of the reaction. The sizes of microspheres prepared by the microwave method were relatively uniform and the microspheres had higher adsorption capacities on Pb2+ and Cd2+. |
