The stopped-flow measurements on the disappearance of alkaline osmium(VII1) at 402 nm indicated a first-order dependence each in [Os(VIII)] and [HCHO]. The pseudo first-order rate constant hobs ([HCHO] & [Os(VIII)]) decreased with increasing [OH-]. The ionic strength, however, had no effect on kobs.
Osmium(VIII) Catalyzed Oxidation of Antimony(III) by Alkaline Hexacyanoferrate(III) and Analysis of Osmium(VIII) in Microamount by a Kinetic Method. -The osmium(VIII) catalyzed title reaction leading to Sb(V) and Fe(CN)4-6 via formation of a catalyst-oxidant complex is utilized for the analysis of
The osmium(VII1)-catalyzed oxidation of D-proline and L(-)-methionine by alkaline hexacyanoferrate(II1) has been studied spectrophotometrically. The reactions follow kinetics different from those of the oxidation of many amino acids investigated earlier, being first order in hexacyanoferrate(II1) an
