Annotation

Procedures were developed for determining glutathione by voltammetry and coulometric titration with electrogenerated oxidants using the biamperometric indication of the titration end-point. Possible mechanisms of the glutathione reaction with electrogenerated halogens are discussed. Microgram amounts of glutathione can be determined in model solutions with an RSD of 1?2%. The oxidation wave of glutathione in the voltammogram is observed at 0.95 V. At higher glutathione concentrations, the wave takes the shape of a peak. Glutathione concentration in the range between 9.15×10(?5) and 2.14×10(?3) M is a linear function of its oxidation wave height at a stationary platinum electrode in a 0.05 M H2SO4 solution. The determination limit for glutathione is 1.9×10(?5) M. The procedures for determining glutathione in human blood were proposed.
