摘　　要：以木质素和壳聚糖为原料,通过共混的方法制备了木质素/壳聚糖共混膜。对膜的物理性能分析表明:膜的平均厚度为0.196 mm,厚度均一;吸水溶胀率为3.76%。采用SEM对膜的微观形貌分析表明,膜的表面有均匀凸起。对Cu^(2+)的吸附性能分析表明,木质素/壳聚糖共混膜对Cu^(2+)的饱和吸附量为106μg/cm2。Lignin/chitosan blend membranes were prepared by blending with lignin and chitosan as raw materials. The physical properties of the membrane showed that the average thickness of the membrane was 0.196 mm and the thickness uniformity, the water swelling rate was 3.76 %. The microstructure of the films was analyzed by SEM, which showed that the surface of the films is homogeneous. The adsorption properties of Cu2＋ showed that the saturated adsorption capacity of lignin/chitosan blend membrane to Cu2＋ was 106 pg/cm2.
