| 摘 要： | 以环氧基为交联桥,将β-环糊精接枝于纤维素纤维上,制备了废水净化纤维,并获得了适宜的制备工艺参数,同时从动力学角度考察了其静态吸附Cu2+的行为。结果表明,环氧化乃该纤维制备之关键,废水净化纤维对Cu2+吸附量可达6.24 mg/g,吸附能力主要来自废水净化纤维β-环糊精中羟基与Cu2+的络合作用,β-环糊精与Cu2+络合比为4∶7。

| Abstract: | In this paper, a kind of new cellulose fiber, which called cleansing fiber, has been prepared and several parameters have been obtained. From adsorption kinetic, its adsorption for Cu2+ has been investigated. The results show, it is vital that cellulose fiber reacts with epichlorohydrin during preparation, the adsorption capacity of the new fiber for Cu2+ reached 6.24 mg/g, the adsorption ability is due to OH- and Cu2+. |
