Abstract
The value of the molar absorption coefficient of ozone in aqueous solutions (2992 ± 71 M–1 cm–1 at 260 nm) is found based on the determination of ozone concentration by iodometry. This value is confirmed by the results of determination of O3 concentration by reaction with the bromide ion and virtually coincides with the maximum absorption coefficient of ozone in the gas phase in the region the Hartley band. In the determinations of ozone concentration in aqueous solutions by direct spectrophotometry, we recommend the value of the molar absorption coefficient ε(О3)260 = 3000 M–1 cm–1.
