脉冲放电等离子体制备壳聚糖铁(Ⅲ)配合物及结构表征

High voltage pulsed discharge plasma on the coordinated reaction for chitosan-Fe(Ⅲ) and structure characterization

以壳聚糖浓度、Fe3+浓度、极板间距和处理时间为影响因素,采用脉冲放电等离子体法制备壳聚糖(CTS)铁(Ⅲ)配合物。并利用红外光谱法(FT-IR)和紫外光谱(UV)进行结构表征。实验结果表明,脉冲放电等离子体可以用来制备CTS-Fe3+配合物,Fe3+浓度、处理时间与吸附量成正相关关系,随影响因素值增大,吸附量增大;壳聚糖浓度、极板间距成负相关关系,随影响因素值降低,吸附量减少。壳聚糖与铁(Ⅲ)发生配位作用的基团可能是-NH2和-COOH。

High voltage pulsed discharge plasma for synthesis of chitosan（CTS）-Fe3＋ complex was studied.Influence factors were chitosan concentration,Fe3＋ concentration,the distance between the electrodes and treatment time.The structure of the complex was characterized by FT-IR,UV.The result showed that Fe3＋ concentration and treatment time were positive.The higher the Fe3＋ concentration and treatment time,the greater the adsorptive capacity.Chitosan concentration and the distance between the electrodes were negative.The higher the chitosan concentration and the distance between the electrodes,the lower the adsorptive capacity.Fe3＋ was coordinated with-NH2,-COOH.
