Iodometric standardization and biamperometric determination of iridium(IV).
Ir(IV) in the concentration range 0.4-0.8 g/l. can be easily determined iodometrically with 0.01M thiosulphate (starch as indicator). The relative standard deviation is 0.2-0.3%. When other coloured ions are present, biamperometric detection is recommended.
