Patent name:一种再生纤维素微孔填料及其制备方法和用途

Invention / Applicant:张俐娜、熊晓鹏、杨光

Patent number / application number:ZL 02147893.7

Authorization / Application Date:2003.06.18

Introduction:

本发明涉及一种再生纤维素微孔填料及其制备方法和用途。该填料的基本组成为:50-90%的纤维素,10-50%的魔芋葡甘聚糖。将4-6%的纤维素NaOH/硫脲水溶液和2-4%的魔芋葡甘聚糖NaOH/硫脲水溶液混合均匀并脱泡,然后注射挤出形成0.5-1mm直径的丝状体在1-10%CaCl2水溶液中于20-40℃下凝固,然后在1-5%的HCl水溶液中再生,用水冲洗后,切成0.5-1mm的圆柱体即为所需填料。由该填料装填的色谱柱可用于生物高分子、合成高聚物等大分子在水或各种有机溶剂中的分级、分离和纯化,尤其适合于分级分子量在5×104-125×104的大分子的分级。
