| 摘 要： | 把高吸水材料封在具超滤功能的醋酸纤维素（CA）皮膜中，制成胶囊。此胶囊浸泡在脲酶水溶液中，水分受高吸水材料的吸引透过皮膜进入胶囊中，脲酶被截留在CA皮膜上，并且与CA上的活性基团相结合，形成CA胶囊固定化脲酶。

| Abstract: | Empty capsule was prepared from cellulose acetate (CA) membrane, which possesses ultrafiltration performance. Highly water-absorbent resin was wrapped in the empty capsule.The CA capsules are submerged in urease solution. Water in the solution is absorbed by the highly water-absorbent resin into the capsule. Urease is retained and immobilized on CAmambrane. |
