| 摘 要： | 以聚丙烯接枝苯乙烯纤维（PP-g-ST）为原料，经过酰基化和胺基化反应制备了四乙烯五胺型螯合纤维（TEPACF），并对酰基化和胺基化反应的条件进行了优化，确定了TEPACF 适合工业化生产的合成工艺。通过扫描电子显微镜、光电子能谱、红外光谱、热重分析、X 射线衍射和机械强度测试进行了表征和性能测试。吸附性能测试结果显示，TEPACF 对In(Ⅲ)的吸附容量达到0.53 mmol·g-1，一定pH 值条件下，TEPACF 对In(Ⅲ)具有很好的吸附选择性。 |

| Abstract: | Tetraethylenepentamine chelating fiber (TEPACF) has been successfully prepared after acylation and amination of propylene fiber grafted with styreneylbenzene(PP-g-ST). The reaction conditions of acylation and amination are optimized. The synthesis technology of TEPACF is suitable for industrialized production. SEM, photoelectron spectroscopy, IR, TG, XRD and mechanical strength test are used to investigate the structure and properties of TEPACF. The result of adsorption performance test shows that the best adsorption capacity of In(III) on TEPACF is 1.53 mmol·g-1, and that TEPACF has good adsorption selectivity to In(III). |
| Keywords: | tetraethylenepentamine chelating fiber polypropylene grafted styrene fiber preparation property |
