The main method for preparing sodium bismuthate is the bromine water oxidation method, but this method yields sodium bismuthate with low purity. Kumada et al. reported an improved synthesis process for bismuthates using an ion exchange method, but these methods require several days of heating.
For the determination of manganese in iron and steel, etc., the manganese being oxidized by it in hot HNO3 or H2SO4 solution to permanganate.
Oxidizer; determination of manganese in iron and steel.
Sodium Bismuthate, is an inorganic compound, which is a strong oxidiser. Sodium Bismuthate converts almost any manganese compound to permanganate, which is easily assayed spectrophotometrically.
