Hydrochemistry of Orumiyeh Lake
Azarbaijan Regional Water Organization
First time the chemical composition of Orumiyeh Lake measured at 1861. Measurements by several authors were done at 1923, 1951, 1973-1983, 1986 and 1994.
In this project, sampling was done by point integral method. This method is applicable in sea and lake which is sampled from defined depths.
In this study, the density of 14 points was measured by piknometry method at 25oC. The precision of results is 0.001 gr/Cm3, shown in table 3. Using the result and the density of 2-salts water solutions, a thermodynamic model was made for prediction of density of saturated solutions on the isometric evaporation diagram of sea water. The model can predict the density of these solutions with less than 1% error. The used application is in appendix.
