SCHEDULED MAINTENANCE
The formation of a 1 : 1 complex with mucic acid (MuH6) has been used for the determination of concentrations of 4.5–25.5 p.p.m. of bismuth(III) at pH 4.0–5.0. The complex exhibits maximum absorption at 245 nm, with a molar absorptivity of 6.5 × 103 l mol–1 cm–1. The method is specific and was applied to the determination of bismuth in pharmaceutical preparations.
