摘要

分析实验室所需样品数量的最小化以及分析操作的牢度的增加是改进与D&D问题相关的放射化学分析的新方向。建立了两种基于微系统的溶剂萃取法从放射性样品中选择性回收55Fe的方法。两种方案都在两种不同的微芯片上对铁溶液进行了测试。并与大规模间歇实验进行了比较。第二种方案基于铁阳离子的反应转移,获得了更好的性能,铁提取率超过80%,更适合使用微通道和极低的接触时间。这项研究已经证明了微流控技术在改进D&D样品分析操作方面的巨大潜力。该方法将进一步用放射性样品进行验证。

Analysis of radionuclides in microsystem: application to the selective recovery of 55Fe by solvent extraction
The minimization of the sample quantities required by analytical laboratories, as well as the increase of the fastness of the analytical operations are emerging axes for improved radiochemical analyses related to D&D issues. Two microsystem-based protocols were developed for the selective recovery of 55Fe from radioactive samples by solvent extraction. Both protocols were tested on iron solutions in two different microchips. The yields of Fe extraction were compared with macroscale batch experiments. Better performances with more than 80% of iron extracted were obtained with the second protocol, which is based on a reactive transfer of the iron cation, and more suited to the use of microchannels and very low contact times. This study already demonstrate the high potential of microfluidic technology to improve analytical operations on D&D samples. This method will further be validated with radioactive samples.
