Реферат:
The Henry's law, Freundlich, and Dubinin–Astakhov, Brunauer–Emmett–Tellerequations, and a new modification of the BET equation are used for thethermodynamic analysis of the activity of water over wide ranges of temperature(260–600 K) and water content (mole fraction 0.3–0.8) in concentrated aqueous solutionsof electrolytes. The solutes considered are H2SO4, CaCl2, LiBr, LiCl, LiI, MgCl2,and NaOH in bulk solutions, and CaCl2 and LiBr dispersed in porous matrixes.The generalized Henry's law equation is found to afford a correct extrapolationof bulk solution properties measured at low and moderate salt concentrations tothe region of low water content. The suggested modification of the BET equationas well as the Dubinin—Astakhov equation give an accurate (relative error lessthan 1%) description of literature data on the humidity—concentration dependenceand can be used for the reliable prediction of this dependence in the region ofintermediate conditions.
