本文讨论的研究旨在调查和记录在受控条件下，传统钠型强酸树脂联合去除钡、镭和硬度的性能。这项研究的原因是:强酸离子交换柱中的钡过早泄漏，缺乏确定影响树脂性能的因素的受控实验室研究，以及缺乏关于再生剂用量对出水质量的影响以及作为运行期间处理水量函数的出水质量的文件。 包括16个参考文献、表格和图表。

The research discussed in this article was conducted to investigate and document the performance of conventional sodium-form strong-acid resins for the combined removal of barium, radium, and hardness under controlled conditions. The reasons for the study were: the premature leakage of barium from strong-acid ion exchange columns, a lack of controlled laboratory studies to determine the factors affecting resin performance, and a lack of documentation regarding the effect of the quantity of regenerant applied on effluent quality and on effluent quality as a function of the amount of water processed during a run. Includes 16 references, tables, figures.
