中文摘要：

通过冷冻干燥，将还原法产生的凝胶状不可溶蛋白制备成具有致密孔隙的海绵膜，无需预处理和无交联剂，并研究了其对Cr（Ⅵ）的吸附性能。结果表明，在60℃、固液比12．5g／L、初始浓度100mg／L下最大吸附量为148．8mg／g，吸附过程符合Langmuir型和Freundlich型等温吸附模型，为吸热过程，物理吸附和化学吸附均起到重要作用。

英文摘要：

Residues of feather reduction reaction were made into a porous keratin sponge film through freez- ing drying without pre-treatment or cross-linking agent. Adsorption of Cr（VI） on the film was studied, and the biggest adsorption capacity turned out to be 148.8 mg/g under 60℃ , solid to liquid ratio of 12.5 mg/mL and in- itial concentration of 100 mg/L, This endothermic adsorption confirmed to both Langmuir and Freundlich model. In this adsorption process, both physical and chemical effects played an important role.
