  • 摘要: 系统研究了聚吡咯（PPy）和壳聚糖（CS）制备的复合电极对金属离子的吸附性能，并采用红外光谱对PPy/CS复合材料的结构和组成进行了表征。结果表明，聚吡咯与壳聚糖结合形成了性能优良的导电聚合物复合材料；PPy/CS复合电极的吸附量与电压和溶液初始浓度成正比；吸附4 h后，对Cu2+的饱和吸附量为30.67 mg·g-1；电极具有良好的再生性和稳定性，再生率达到92.0%；复合电极对不同种类的金属离子都有较好的吸附效果，且吸附过程符合二级动力学模型。
    Abstract: The adsorption properties of polypyrrole (PPy) and chitosan (CS) composite electrodes on metal ions were systematically studied. Furthermore, the PPy/CS composite structure and composition were determined using infrared spectroscopy. The results showed that the combination of polypyrrole with chitosan led to a conductive polymer composite exhibiting good performance. The PPy/CS composite electrode adsorption capacity was proportional to the voltage and initial concentration of the solution. Under optimal conditions and after 4 h of adsorption, the adsorption capacity for Cu2+ was 30.67 mg·g-1. The electrode also exhibited good reproducibility and stability, with a regeneration rate of 92.0%. In summary, the composite electrode showed good adsorption for different types of metal ions, and the adsorption process was in line with a second-order kinetic model.
