The vapour pressures over saturated aqueous solutions of cadmium chloride, cadmium bromide, cadmium iodide, cadmium nitrate, and cadmium sulphate

Separation of Cd and Ni from multicomponent aqueous solutions by nanofiltration and characterization of membrane using IT model

“…The values of osmotic coefficients of the salts studied here are taken from the literature [39][40][41]. It is important to note that, due to the concentration polarization, the salt solution at the membrane surface cannot be assumed to be dilute.…”

Temperature Dependence of Vapor Pressures over Saturated Aqueous Solutions at Invariant Points of the NaCl + KCl + H2O, NaCl + NaNO3 + H2O, KCl + KBr + H2O, KCl + KI + H2O, KCl + KNO3 + H2O, and KCl + K2SO4 + H2O Systems

“…Some information about vapor pressures in binary systems exists, but usually at 298.15 K, in tabulations of saturated solutions which are used to control humidity in biological experiments. 4,5,7,8,43 In the continuation of studies on the vapor pressure of water saturated with one inorganic salt, [46][47][48][49][50][51][52][53][54][55][56][57] in this work the saturated solutions in ternary systems in the T ) 278 K to T ) 322 K temperature range are considered. Determined vapor pressures are also expressed in terms of the water activities a 1 and by combining them with solubilities (taken from the literature) in terms of osmotic coefficients φ.…”

Vapor Pressure of Saturated Aqueous Solutions of Potassium Sulfate from 310 K to 345 K

“…The dependence on temperature of the vapor pressure of saturated aqueous solutions has been already determined for most of the inorganic salts, particularly halides, sulfates, and nitrates [1][2][3]. However, for the case of potassium sulfate the available information is surprisingly scarce and restricted to the temperature range 273 K ≤ T ≤ 323 K [4][5][6][7] plus one evaluation at 374 K [8].…”
