A new strong base anion exchange resin (LSL-1) was synthesized by grafting trimethylamine groups onto polystyrene-divinylbenzene microspheres and used for the selective recovery of Re(VII) from U(VI)-containing effluent. The morphology and structural properties of LSL-1 were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The adsorption mechanism is discussed. In both batch and column experiments, LSL-1 showed excellent enrichment capacity for Re(VII). This study demonstrates a new approach for the separation and recovery of Re(VII) from U(VI)-containing effluent by using amino-modified polystyrene-divinylbenzene microspheres.

使用三甲胺功能化强碱阴离子交换树脂吸附和分离 Re(VII)

通过将三甲胺基团接枝到聚苯乙烯-二乙烯基苯微球上合成了一种新型强碱阴离子交换树脂 (LSL-1)，并用于从含 U(VI) 的流出物中选择性回收 Re(VII)。通过扫描电子显微镜、傅里叶变换红外光谱和X射线光电子能谱对LSL-1的形貌和结构特性进行了表征。讨论了吸附机理。在批量和柱实验中，LSL-1 对 Re(VII) 显示出优异的富集能力。本研究展示了一种使用氨基改性聚苯乙烯-二乙烯基苯微球从含 U(VI) 流出物中分离和回收 Re(VII) 的新方法。
