Abstract
To develop absorption procedures for the removal of sulfur dioxide from ind ustrial gases, two water-salt systems absorbing SO2 were studied. The syste ms involve NaCl (at 298, 323, and 348 K) and Na2SO3 (at 298 K) as main supp orting electolytes. The logarithms of the mean ionic activity coefficients of sulfurous acid In gamma(+/-) in the entire range of total ionic strength s under study were obtained from the data of direct measurements for these two systems.
