Dependency of partition equilibrium of iodine between air and aqueous solution containing sodium hydroxide upon temperature and concentration

Abstract

The overall partition of iodine between air and aqueous solution containing sodium hydroxide is very complicated due to the complex reactions of iodine dissolved in the aqueous phase. The equilibrium constants of the several elementary reactions which influence the overall partition were measured for the range of 10 ° to 80 °C. Then the dependencies of the overall partition of iodine upon both temperature and concentration were theoretically analyzed by an approximate method. © 1974, The Society of Chemical Engineers, Japan.
