Abstract: A kind of crosslinked films based on bayberry tannin/konjac glucomannan(KGM)/rice flour was prepared and analyzed by FT-IR. The adsorption behaviors of the films to copper and zinc ions were investigated. The results indicated that the adsorption capacity for Cu2+ and Zn2+ reached a maximum value of 12.79 mg/g and 6.13 mg/g respectively at 25℃ and pH 5.0 when the initial concentration of Cu2+ and Zn2+ was 200 mg/L. The adsorption capacity was un-significantly increased with the rise of temperature. The adsorption isotherms of copper and zinc ions could be well described by the Freundlich equation. The adsorption kinetics data could be fitted by the pseudo-second-order model. In addition, crosslinked films based on bayberry tannin can selectively remove Cu2+ from the mixture solution of Cu2+ and Zn2+.
