Preparation method of high-purity chloroiridic acid and obtained high-purity chloroiridic acid

The invention discloses a preparation method of high-purity chloroiridic acid and the obtained high-purity chloroiridic acid. The preparation method of the high-purity chloroiridic acid comprises the following steps: performing alkali fusion on iridium powder, performing ultrasonic desalination, and performing ultrasonic dissolution on a solid obtained by ultrasonic desalination by using hydrochloric acid to obtain the high-purity chloroiridic acid. According to the method, the unique ultrasonic cavitation effect of ultrasonic waves is utilized in the desalting and dissolving process, dissolution of alkali metal ions is facilitated, and impurity residues are reduced; the dissolution of iridium oxide in hydrochloric acid is promoted, nitric acid is avoided, the product does not contain nitrogen element impurities, meanwhile, treatment of waste gas containing nitric oxide is not needed, pollution is reduced, and investment is saved. 本发明公开了一种高纯度氯铱酸的制备方法及所得高纯度氯铱酸。所述高纯度氯铱酸的制备方法,包括将铱粉进行碱熔后超声脱盐，然后将超声脱盐得到的固体用盐酸超声溶解得到
