摘要

这项研究考察了 106Ru 在模拟技术介质和来自 VVER 反应堆核电站的液态放射性废物溶液中的状态，以及放射性核素的物理化学状态对离子交换和超滤处理方法效率的影响。在研究过程中，探索了放射性核素在成分复杂的溶液中离子态和非离子态的存在区域。此外，还确定了含 106Ru 颗粒的大小分布。研究表明，在中性和微碱性 pH 值区域，106Ru 与聚硼酸根离子会形成复杂的化合物，从而导致钌放射性核素对液态放射性废物的净化效率降低。

Influence of Iron(III) Hydroxo Forms and Boric Acid on the State of Ruthenium-106 in Aqueous Solutions

The work examines the state of ¹⁰⁶Ru in solutions simulating technological media and liquid radioactive waste from nuclear power plants with a VVER reactor, as well as the influence of the physicochemical state of the radionuclide on the efficiency of ion exchange and ultrafiltration treatment methods. During the study, the regions of existence of ionic and nonionic states of the radionuclide were explored in solutions of complex composition. In addition, the size distribution of particles containing ¹⁰⁶Ru were established. The formation of complex compounds of ¹⁰⁶Ru with polyborate ions in the neutral and slightly alkaline pH region has been shown, which leads to a decrease in the efficiency of decontamination of liquid radioactive waste from ruthenium radionuclides.
