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

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.
