| 摘 要： | 本文用20%的NaOH溶液对棉纤维的预处理、醚化、接枝合成工艺进行了优化;在不同条件下,研究了咪唑季铵盐棉纤维对DOSO~-_3的吸附性能.结果表明,用NaOH预处理棉纤维后,在适当的条件下醚化棉纤维素,再用氢氧化钠作催化剂,按3 g环氧基纤维素醚与10 mL甲基咪唑配比接枝,得到白色味唑季铵盐纤维素.用咪唑季铵盐棉纤维对DOSO~-_3进行吸附,吸附率可达91.8%,吸附效果令人满意.

| Abstract: | The paper investigates the method of using 20% NaOH to optimize the synthesize crafts of the pretreatment,the etherization,and the graft.Under different conditions,absorbing quality of the Quaternary Ammonium Salt cellulose to DOSO_3~- has been studied.The result shows:after using NaOH pretreatment cotton cellulose, under proper condition,the cellulose is etherified,and using NaOH as a catalyst,ac- cording to the proportion of 10ml/3g(methyl imidazole/epoxy cellulose ether),the epoxy cellulose ether iS grafted,and white polyamine type Quaternary Ammonium Salt cellulose is received.The ammonium salt cellulose can easily absorb DOSO_3 and adsorption efficiency reaches 91.8%.It has good absorbing property. |
