Crystallization from solar evaporation is used to produce salts The solution becomes increasingly concentrated until it reaches saturation then the the the salts begin to crystallize In the the the current study three solutions
in in varied concentrations were heated to temperatures of of 25°C and and 45°C The The density and and the the concentration of of the the the cations were measured The The experimental results indicate that the the the fastest evaporation rate was at at at at at at at 45°C making the the process of producing sodium chloride salt more efficient Keywords: crystallization Dead sea evaporation ion ion ion chromatograph sodium chloride The effects of of humidity and and temperature on on on the evaporation rates of of sodium potassium calcium and and magnesium salt solutions

The The Dead Sea contains commercially important salts that are extracted by means of of of a a a a a a a a a a a a a a a a solar evaporation evaporation process The The purpose of of of of this research is is to to test the the the the effects of of of of humidity and temperature on on on on on on on on the the the the evaporation evaporation rates of of of the the the the solutions
solutions
in in in order to to optimize the the the the salt crystalization process Three solutions
solutions
were were tested at at at at at at at at at at different concentrations in in in in a a a a a a a a a a a a a a a a a a shaking bath at at at at at at at at at at 25°C and and 45°C Changes in in in in density and and and cation concentration concentration were were studied over time From the the the the results it it it was found that as as as as as the the the the humidity decreased and and the the the the temperature increased increased the the the the evaporation rate increased Keywords: evaporation rate humidity salt solutions
