Separation of Cation Isotopes by Complexation with Crown Ethers

该项目是在分析和表面化学领域 以及溶质提取领域。 Echegoyen教授 将研究溶液热力学与 使用天然存在的和 合成制备的冠醚离子载体。 这项研究将使用化学或电化学制备的 蒽醌取代冠醚的阴离子自由基或二价阴离子 醚离子载体。 涉及这些的萃取平衡 水溶液中具有选定阳离子同位素的物种 将使用原子吸收光谱法进行定量， 电子顺磁共振谱 结果 在这项研究中获得的信息将对 同位素纯化过程。

This project is in the area of Analytical and Surface Chemistry and in the subfield of solute extraction. Professor Echegoyen will study the solution thermodynamics associated with the extraction of selected isotopes using naturally occurring and synthetically prepared crown ether ionophores. This research will use chemically or electrochemically prepared anion radicals or dianions of anthraquinone substituted crown ether ionophores. Extraction equilibria involving these species with selected cation isotopes from aqueous solution will be quantified using atomic absorption spectroscopy and electron paramagnetic resonance spectroscopy. The results obtained in this research would have a profound affect on isotope purification processes.
