摘要

本文制备了以Fe3O4纳米微球为核心，具有核壳结构的缬霉素功能化纳米磁性固相萃取剂(VFE)。通过SEM、PPMS、XRD、FT-IR、TGA、EDS、ICP-MS、AAS等手段对相关性能进行了表征和测试。得到了最佳萃取条件:温度50℃，#176℃以上，pH不小于9.3，萃取平衡时间约35 min。循环性能实验表明，经过5次萃取-洗脱循环后，铷离子的提取率仍可达85.3%。模拟卤水、工业废水和生活废水的萃取实验表明，VFE对这些水体系中的铷离子具有良好的选择性萃取能力。本研究有望为水体系中铷离子的分离、提取、富集和检测提供一种新方法或新材料。

Preparation, Characterization and Extraction Performance of Rubidium Ions in Water System

In this paper, a valinomycin-functionalized nano-sized magnetic solid-phase extractant (VFE) with the core-shell structure and the Fe3O4 nanospheres as the core is prepared. Related performances are characterized and tested by SEM, PPMS, XRD, FT-IR, TGA, EDS, ICP-MS, and AAS. The optimal extraction conditions are obtained, namely, temperature 50 and#176;C or higher, pH not less than 9.3, and equilibrium extraction time about 35 min. Recycling performance experiments show that the extraction ratio of rubidium ions after 5 extraction-elution cycles is still up to 85.3%. Extraction experiments with the simulated brine, industrial wastewater, and domestic wastewater show that the VFE exhibits good selective extraction ability for rubidium ions in these water systems. This research is expected to provide a new method or a new material for the separation, extraction, enrichment, and detection of rubidium ions in water systems.
