摘　　要：以戊二醛为交联剂,制备交联壳聚糖膜(CCS),研究其对不同偶氮染料的吸附脱色机制;以甲基橙为对象染料,比较了不同吸附剂的吸附性能.结果表明:结构复杂的染料,其脱色效果较差;以交联壳聚糖膜作为吸附剂,其稳定性比单纯壳聚糖膜好,脱色效果优于活性碳.The crosslinked chitosan membrane was prepared with Glutaraldehyde as a crosslinking reagent. The ability of adsorption was studied. The adsorption of azo dyes was performed as a function of dye categories and different kinds of adsorbents. The adsorption capacities of chitosan were comparatively high when the structure of dyes molecular went simple, and the adsorption rate was higher than active carbon.
