Step 1, Electrodissolution: Add hydrochloric acid solution 4 and iridium powder raw material 5 to U-shaped electrolytic cell I; The U-shaped electrolytic cell I is made of acid-resistant material, and non-metallic conductive electrode 2 is provided in the U-shaped electrolytic cell; The temperature of the hydrochloric acid in the electrolytic cell is controlled at 100-115°C, and an alternating current of 5-80 volts and 2-50 amperes is applied across the electrodes to perform constant voltage electrolysis until the iridium powder dissolves to form a chloroiridium acid aqueous solution; The hydrochloric acid is of analytical grade purity, and the concentration of hydrochloric acid is 8-12 mol/L; the weight ratio of hydrochloric acid to iridium powder is 3:1-100:1; The electrolysis time of the constant voltage electrolysis is 1-15 hours; Step 2, Filtration: Filter the obtained chloroiridium acid aqueous solution to filter out unreacted iridium powder; Step 3, Concentration: The filtered aqueous solution of chloroiridic acid is distilled to remove excess hydrochloric acid and water, yielding a concentrated chloroiridic acid solution. The iridium content of the concentrated chloroiridic acid solution is 1.0–3.5 mol/L. Step 4, Crystallization: The obtained concentrated chloroiridic acid solution is crystallized in a constant-temperature crystallization furnace at 90–125°C for 5–24 hours to obtain Iridium(III) chloride hydrate IrCl3 • 3H2O. |
