چکیده
“Salting out effect” means that the addition of an organic solvent to an aqueous solution of a salt will reduce the solubility of salts and thus induce its precipitation.1 Therefore, the investigations of the physicochemical properties of inorganic salts in organic solvents – water, such as solubility data together with density, refractive index and so on, are of great scientific importance. Various systems of salt and mixed solvent systems have been investigated to assess the potential applicability of such method as a technique for separation of salts. Many of the reports focus on systems composed of alkaline metal chlorides, alcohols, and water. For example, the properties of systems of alcohol (propan-1-ol, propan-2-ol, pentan-2-ol, pentan-3-ol, 2-methylbutan-2-ol, 2-methylbutan-1-ol, and pentan-1-ol) + MCl (M = Na, K) + water were systematically studied by Gomis et al.2–5 Moreover, physicochemical properties of NaNO3 + H2O + poly(ethylene glycol),6 KNO3 + H2O + propan-2-ol,7 and LiNO3 in organic solvent (methanol, ethanol, propan-1-ol, propan-2-ol and butan-1-ol)8 were reported.

The solubility of KNO3 in the mixed solvent (water 85%+methanol 15%) were determined by using solvent evaporating method at different temperatures (25, 30, 40, 50, 60 ;C). In addition the equilibrium constant of ion pair formation, KIP, for K+NO3 – ion-pair on the basis of Fuoss contact ion pair model was calculated. Upon choosing the extended Debye-Hückel model for estimating the mean activity...

We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...
متن کاملThermodynamics of the solubility of potassium nitrate in the mixed solvent, Ethanol+Water, and the related Ion-association
Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...
