| 摘 要： | 以腈纶为起始原料,分别经水合肼、乙二胺、二乙烯三胺预交联后,以N,N-二甲基甲酰胺作溶剂与硫化钠反应,合成了三种携硫代酰胺功能基可达6.8mmol/g(干纤维)的螯合功能纤维。探讨了溶剂、反应温度、反应时间、pH等对反应产物的影响,利用红外光谱、元素分析、热稳定分析、重量分析等对该螯合纤维的结构、性能等进行了表征,并就其对金属离子的吸附性能进行了研究。结果表明:螯合纤维对Au3+、Ag+、Pd2+等贵金属离子具有良好的吸附性,对Ag+的吸附容量可达1510mg/g(干纤维),对Au3+、Pd2+的吸附容量分别为800mg/g(干纤维)和21.2mg/g(干纤维)。 |

| Abstract: | Three kinds of thioamide-group chelating fiber were synthesized by cross-linking of initial polyacrylonitrile(PAN) fiber with anhydrous hydrazine, ethylenediamine, diethylenetriamine respectively and following chemical modification with sodium sulfide. The maximum content of thioamide functional group was 6.8 mmoL/g(dry fiber). The influence of solvent, reaction temperature, reaction time and pH value was discussed. The structure of the chelating fiber was characterized by IR, EA, TG and weight analysis. The conditions of synthesis for thioamide-group chelating fiber was studied. The adsorption properties of chelating fiber for metal ions such as Au3 ,Ag ,Pd2 were preliminarily discussed. It was found that chelating fiber possessed high capacities for Ag (1510 mg/g), Au3 (800 mg/g) and Pd2 (21.2 mg/g). |
