铱被用作几种合金的硬化剂和新一代催化剂。因此，其回收利用是一个高度优先的挑战。研究了不同四氟溴代物MBrF_4（M = K，Rb，Cs）和M（BrF_4）（2）（M = Ba）与金属铱的反应，以使后者转化为易溶形式，从而有利于贵金属的进一步回收。确定了产物的组成，提出了相应的反应方案，确定了适宜的反应条件。
Iridium is used as a hardening agent in several alloys and as a new-generation catalyst. Therefore, its recycling is a high-priority challenge. The reactions of various tetrafluorobromates MBrF4 (M = K, Rb, Cs) and M(BrF4)(2) (M = Ba) with Ir metal were investigated in order to transform the latter to an easily soluble form to facilitate the further recovery of the noble metal. The compositions of the obtained products were determined, corresponding reaction schemes are suggested, and proper conditions for the reactions were established.
