摘要

结合辐射接枝聚合和化学修饰，通过三步处理，成功地制备了偕胺肟化尼龙66纤维。通过傅里叶红外光谱（Fourier transform infrared spectroscopy, FTIR）仪和扫描电子显微镜（Scanning electron microscopy, SEM）对初始的和修饰后的尼龙66纤维进行化学结构和微观形貌表征。结果表明，偕胺肟基团以共价方式连接到尼龙66纤维上。通过模拟核工业废水的吸附研究表明，PA66-,g,-PGMA-IDPAO纤维对铀酰离子有高的吸附效率（91.3%）和吸附选择性，具有巨大的潜在工业应用价值。

Abstract

Amidoximated nylon 66 fibers were successfully synthesized by combining radiation-induced graft polymerization with chemical modification through a three-step approach. The chemical structure and micromorphology of the pristine and modified nylon 66 fibers were characterized by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The results showed that amidoxime groups were covalently connected to nylon 66 fibers. The results of adsorption of uranium in simulated nuclear industry effluents showed that amidoximated nylon 66 fibers performed a high adsorption efficiency (91.3%) and excellent selectivity for uranium adsorption, indicating that amidoximated nylon 66 fibers have potential application in industry.
