Abstract

Abstract:

A cross.linked chitosan vanillin Schif base was synthesized by formaldehyde under microwave radiation,whose structure was then characterized by means of IR and XRD.The solubility of the product·in acidic solutions was also compared with that of chitosan vanillin Schif base using UV absorption spectrum.The adsorption experi-ment showed that.as compared with chitosan vanillin schif base and cross.linked chitosan by form aldehyde,the
product is of different adsorption capability for some metal ions.Moreover.as the product possesses excellent selec-tive adsorption for Cu²⁺ and is insoluble in acid conditions.it can be used as a selective adsorbent of Cu²⁺ .

Key words: chitosan, modification, microwave radiation, adsorption
