Technology used to produce high purity anhydrous rubidium perrhenate on an industrial scale from high purity perrhenic acid and rubidium nitrate by the ion-exchange method is described in this paper. This material is dedicated to catalyst preparation, therefore, strict purity requirements have to be fulfilled. These are satisfied by combining rubidium ion sorption on an ion exchange column and the subsequent elution of the high purity perrhenic acid solution, followed by crystallization, evaporation, purification, and drying. In the current study, rubidium and rhenium contents were found to be 22.5 wt.% and 55.4 wt.%, respectively, while contaminations were as follows: <2 ppm As, <2 ppm Bi, <5 ppm Ca, <5 ppm Cu, <3 ppm Fe, <10 ppm K, <3 ppm Mg, <5 ppm Mo, <2 ppm Na, <5 ppm Pb, and <3 ppm Zn.
本文介绍了通过离子交换法从高纯度高铼酸和硝酸铷中大规模生产高纯度无水高铼酸铷的技术。这种材料用于催化剂制备，因此必须满足严格的纯度要求。通过在离子交换柱上吸附铷离子，随后洗脱高纯度高铼酸溶液，然后进行结晶、蒸发、纯化和干燥来满足这些要求。在当前研究中，发现铷和铼的含量分别为22.5 wt.%和55.4 wt.%，而杂质含量如下：砷<2 ppm、铋<2 ppm、钙<5 ppm、铜<5 ppm、铁<3 ppm、钾<10 ppm、镁<3 ppm、钼<5 ppm、钠<2 ppm、铅<5 ppm和锌<3 ppm。
