Distribution coefficient (Kd) data provides the analyst with a powerful set of tools for designing elemental chemical separations. While considerable Kd data exists in the literature for traditional anion and cation exchange resins, a comprehensive Kd study for the majority of the periodic table has not been published to date for several newer Eichrom extraction chromatographic resins. Kd values for the sorption of 41 different of elements on TEVA, TRU, UTEVA, and Diphonix resin were determined in this work. The power of Kd data in designing chemical separations is then demonstrated through development of separation methods for several challenging chemical separations including U/Mo/Te, Zr/Nb/Mo, and Cd isolation. Separation methodologies are finally applied to soil samples, where the ability for each separation to perform under complex matrix conditions is evaluated.

基本分布系数数据和使用eichrom萃取色谱树脂的分离。

分布系数（Kd）数据为分析人员提供了一套功能强大的工具，用于设计元素化学分离。尽管传统阴离子和阳离子交换树脂的文献中已有大量的Kd数据，但迄今为止，尚未针对多种新型Eichrom萃取色谱树脂发表有关大多数元素周期表的全面Kd研究报告。在这项工作中，确定了在TEVA，TRU，UTEVA和Diphonix树脂上吸附41种不同元素的Kd值。然后，通过开发用于多种挑战性化学分离的分离方法，包括U / Mo / Te，Zr / Nb / Mo和Cd分离，证明了Kd数据在设计化学分离中的作用。分离方法最终应用于土壤样品，
