经环氧活化的棉杆纤维素醚分别与3-羟基-1，5-二氯杂环庚烷和3-羟基-1，5-二氮杂环辛烷反应，制备了二种氮杂冠醚化棉杆纤维衍生物，测定了它们对金属离子的吸附性能及溶液pH值的影响。结果表明二者对Hg2+，Cd2+有较好的吸附性能，对Cu2+的吸附-解吸-再吸附实验表明，二种氮杂冠醚化棉杆纤维衍生物具有重复使用的性能。
Abstract：The azacrown ether cotton stalk cellulose derivatives (Cell-A, Cell-B) were synthesized by reaction of 3-hydroxyl-1, 5 -diaza-cycloheptane or 3- hydroxyl -1, 5-diaza-cyclooctane with epoxy-activated cotton stalk cellulose powder(40 -60 ). The nitrogen amount of Cell-A and Cell-B is 0. 556mmol/g and 0. 561mmol/g respectively. The adsorption properties of the azacrown ether cellulose derivatives were determined for Mg2+ , Cr3+, Fe3+ , Co2+, Cu2+, Cd2+, Hg2+ and Pb2+. The results of static adsorption experiment showed that they have good adsorption capacity for Cu2+, Cd2+ and Hg2+. The adsorption amount of Cell-B is higher than Cell-A for Cd2+ and Hg2+. When the PH value of solution was increased, the adsorption capacity of ligands increased for mettalic ions.The results of the kinetic adsorption test for Cu2 + indicated that Cell-A and Cell-B have reusing character and can be reused as an anion exchanger.
