One possible method for removing radium from waters is to use zeolites. The research carried out and described in the article was aimed at examining a wide spectrum of zeolites: natural (clinoptilolite) and synthetic (NaP1, 13X, 3A, 5A), as some of them show the high efficiency of radium removal from all types of water, it means the drinking water and brines as well. Characteristic of zeolites, as the percentage of zeolite phase and other components, was performed by XRD analysis. For radium removal testing two samples of brines, collected from underground mine outflow, were used. Studies have confirmed, that the best efficiency of radium removal from mine water was found for the NaP1 type zeolite, produced on the base of fly ash with use of NaOH. Experiments showed that clinoptilolite, 3A, 5A and 13X have significantly lower efficiency of radium removal.

不同合成沸石去除水中镭的应用研究

从水中除去镭的一种可能的方法是使用沸石。该文章中进行和描述的研究旨在检查各种沸石:天然(斜发沸石)和合成沸石(NaP1、13X,3A,5A),因为其中一些显示出从所有类型的沸石中去除镭的高效率。水,它也意味着饮用水和盐水。通过XRD分析来确定沸石的特征,即沸石相和其他组分的百分比。为了进行除镭测试,使用了两个从地下矿井流出处收集的盐水样品。研究证实,对于NaP1型沸石,发现其从矿井水中除镭的最佳效率,该沸石是在粉煤灰的基础上使用NaOH生产的。实验表明,斜发沸石3A,
