摘要

提出了一种研究双相体系萃取动力学的新方法，利用衰减全内反射（ATR IR）几何形状下红外吸收光谱的延时记录。通过研究不同萃取剂从酸性和碳酸盐介质中萃取铕、钇和铯离子的过程，验证了该方法的可行性。提出了与配体官能团逐步配位的机理。计算了含铕萃取体系的萃取动力学常数。与传统方法相比，新方法的主要优点是小型化和快速。

Kinetics study of fission products’ extraction with attenuated total internal reflection IR spectroscopy

A new method for extraction kinetics studying in a biphasic system using time-lapse recording of IR absorption spectra in the attenuated total internal reflection (ATR IR) geometry is developed. The method is examined by studying the extraction process of europium, yttrium and cesium ions with various extractants both from acidic and carbonate media. The mechanism of step-wise coordination with functional groups of the ligand is proposed. The extraction kinetics constants are calculated for the extraction systems with europium. The main advantages of the new method are miniaturization and rapidity, compared to classical methods.
