Evaluation of salt effects on some thermodynamic properties of Urmia Lake water

摘要: In this study some thermodynamic parameters including freezing point, boiling point and the vapor pressure of Urmia Lake salt water were investigated as important environmentally monitored physicochemical properties Lake. regard concentration is chiefly responsible for the modification the which affects its overall environmental and ecological characteristics. On other hand, now supposed to be most convenient place many rare aquatic species therefore interpreted unique from viewpoint qualitative characteristics. For goals sampling analysis where performed in two wet dry periods lake order represent extremes lake’s environmental variability. Prevailing chemical ions body determined used estimation relative thermodynamic coefficients acquisition vapor the Urmia water. Interpolated calibration curves plotted changes studied parameters versus a variety concentrations indicating linear relationship between and the prevailing The then formulated simplify the any salinity conditions. Real sample analysis also showed very good agreement estimated observed values.
