Synthesis and Characterization of the Complex of Chitosan-immobilization Ferrous-N-salicylidene Glycine Schiff Base

Abstract

Abstract: Chitosan′s ramification derived from chitosan and the schiff base and their ferrous complex have been synthesized and characterized by elementary analysis, IRand UV-Vis spectra, fluorescence spectrophotometry and thermal analysis.The Schiff base was derived from salicyl aldehyde and glycine.It was found that the coordination is realized through binding of Nin chitosan with the Fe(Ⅱ) in ferrous N-salicylidene glycine complex.The effect of this complex on the elimination of superoxide anion waSInvestigated by the decrease in the absorbance at 550nm in the system of vitamin B₂-hydroxylamine-anilinesulfonic acid-N-(1-naphthyl)ethylenediamine.Comparing the effect of ferrous N-salicylidene glycine complex on the elimination of superoxide anion with chitosan-ferrous-Schiff base complex′, it was found that the eliminative effect of the chitosan-ferrous-schiff base complex decreased in a sort, but still remained the stronger ability of eliminating superoxide anion.
