As metallic mercury (Hg) has a relatively high vapor pressure, it is increasingly important to study on the mercury emission rate to the atmospheric air from the stand-point of environmental protection. A semi-theoretical formula on vaporization rate of Hg through the top box using in Cl₂-caustic electrolysis was proposed with some assumptions. In order to calculate this formula and elucidate the mechanism of the dissolution of Hg, solubilities of Hg in 0.1N NaOH and distilled water were determined at 20-80℃ under the conditions in the absence or presence of dissolved oxygen. As the results, Hg emission might be small unless the convection of the solution and Hg in top box were violent, but, this is not the case, any appropriate device was required for the protection of the environmental pollution by mercury vapor emission at NaCl electrolysis plants.
