In this work, the possibility of using electrodialysis for the treatment of liquid low-level radioactive waste was investigated. The first aim of the research was to evaluate the influence of the process parameters on the treatment of model solutions with different compositions. Subsequent experimental tests were conducted using solutions containing selected radionuclides (Co and Cs), which are potential contaminants of effluents from nuclear power plants, as well as components often found in waste generated from industrial and medical radioisotope applications. The results of the experiments performed on real radioactive waste confirmed that electrodialysis was a suitable method for the treatment of such effluents because it ensured high levels of desalination and rates of decontamination. The most important parameters impacting the process were the applied voltage and electrical current. Moreover, this research shows that the application of the ED process enables the separation of non-ionic organic contaminants of LLW, which are unfavorable in further stages of waste predisposal.
在这项工作中，研究了使用电渗析处理液态低放放射性废物的可能性。该研究的首要目标是评估工艺参数对不同成分模拟溶液处理效果的影响。随后使用含有选定放射性核素（钴和铯）的溶液进行了实验测试，这些放射性核素是核电站废水的潜在污染物，也是工业和医用放射性同位素应用产生的废物中常见的成分。对实际放射性废物进行实验的结果证实，电渗析是处理此类废水的合适方法，因为它能确保高水平的脱盐和去污率。影响该过程的最重要参数是施加的电压和电流。此外，这项研究表明，电渗析工艺的应用能够分离低放废物中的非离子有机污染物，这些污染物在废物预处理的后续阶段是不利的。
