From: Deliquescence of NaCl–NaNO3, KNO3–NaNO3, and NaCl–KNO3salt mixtures from 90 to 120°C
Model predictions of brine (a) % relative humidity and (b) solution composition as a function of temperature at the deliquescence point for a NaCl–NaNO3–KNO3 mineral assemblage (Ref. 8). Predictions were made with EQ3/6 geochemical code and the high temperature Pitzer ion interaction thermodynamic data base. Triangles, circles, squares, and diamonds represent NO3, Na, K, and Cl concentrations.
