文章通过碱活化棉纤维，经环氧氯丙烷环氧化和高碘酸钠氧化制备双氧化棉纤维，先后接枝β-环糊精和端氨基超支化聚合物，制备了一种棉纤维基吸附剂。对制备的吸附剂进行了表征，并通过模拟废水吸附实验优化了吸附剂制备过程中高碘酸钠对棉纤维的氧化工艺。结果表明，当高碘酸钠浓度为12 g/L，50℃水浴氧化反应3 h制备的吸附剂对Pb2＋和刚果红的吸附容量达到最大值，最大吸附容量分别为65.7 mg/g和223.7 mg/g。

In this paper, a kind of adsorbent was prepared by graftingβ-cyclodextrin and amino-terminated hyperbranched polymer after the alkalization of cotton fiber through epoxy chloropropane epoxidation and sodium periodate oxidation. The prepared adsorbent was characterized. The oxidation technology for cotton fiber was optimized according to adsorption experiments with model wastewater. The result indicated that the cotton fiber-based adsorbent has best adsorption capacity to Pb2+and Congo red when the cotton fibers were oxidized with 12 g/L sodium periodate at 50℃for 3 h. The maximum adsorption capacity to Pb2+and Congo red can reach 65.7 mg/g and 223.7 mg/g respectively.
