Summary Manganese(VII) (0–120 μg) can be determined spectrophotometrically at 548 nm after its adsorptive extraction at pH 6 as its trimethylene-bis(triphenylphosphonium) ion pair with microcrystalline naphthalene after dissolution of the solid phase in chloroform. The effects of pH, reagent conditions and diverse ions are reported. The system has been applied to the determination of manganese in a range of steels. For the determination of 60 μg of manganese the relative standard deviation was 0.61%.
