Abstract
The determination of dissolved oxygen using the Winkler method in an electrolyte solution such as brine or mother liquid used in a salt manufacturing process is discussed. The solubility of oxygen in pure water at 298-363 K conforms to the value proposed by Winkler. And the measured values of brine obtained from salt farms using the Winkler method and the van Slyke-Neil method are almost the same. It is believed that the Winkler method is effective for measuring the solubility of dissolved oxygen at high temperatures.<BR>On the other hand, the salting-out parameters of oxygen are calculated using the relationship between the solubility of oxygen and the ionic strength in NaCl, MgCl2, CaCl2, KCl solutions, respectively. The solubility of oxygen in various mixed electrolyte solutions is accurately estimated by using the salting-out parameters and the ionic strength at 343 and 363 K. From these results, it is believed that the solubility of oxygen can be calculated from the composition of electrolyte solution.
