Ozone dissolution in aqueous systems treatment of the experimental data

The major concern of the paper was to establish how the treatment method of the experimental data collected during a semibatch ozone dissolution process in aqueous systems using gas-liquid absorbers could influence the determination of the fundamental process parameters such as ozone solubility (or the Henry's law constant values) and mass transfer coefficients. Statistically the best were the sigmoidal Boltzmann and Weibull fits, however, they provide the product of the mass transfer coefficient (k(L)a) and the saturation Ozone concentration in the liquid phase. In order to determine the Henry's constant an independent evaluation of k(L)a is necessary. Ozone decomposition term might play relatively small role in the overall mass balance of ozone in the liquid phase so the question of the reaction order of ozone decomposition in such a case may be of less significance.
