Catalytic Determination of Trace Amounts of Iridium As Chloride Complexes
A procedure was developed for the determination of iridium as chloride complexes by its catalytic action on the oxidation reaction of Sulfarsazene with potassium periodate at pH 5.6. The analytical range was 1 × 10−5 – 1 × 10−3 μg/mL iridium. The accuracy of the procedure developed was confirmed in the determination of iridium in model solutions by the standard addition method. The relative standard deviation did not exceed 6%.
