Solubility of oxygen in electrolyte solutions

Knowledge of oxygen saturation solubilities is important for the design of waste water treatment and aerobic fermentations. Currently the oxygen polarographic probe is usually used to measure partial pressures of dissolved oxygen. For the determination of physical mass transfer coefficients in synthetic fermentation media, the oxygen saturation solubility need not be known if the underlying equations are linear; knowledge of the oxygen partial pressure will suffice. However, if the performance of a fermentor is to be determined, especially if oxygen is a
