Sažetak
Words: seawater, saltwork, evaporation, crystallization
In addition to the field measurements and laboratory experriments mathematical models are also included in modern studies of the seawater evaporation. They usually describe two main cases:
1. equilibrium evaporation, i.e. permanent contact of the brine with all previously formed solids
2. fractional crystallization, i.e. complete elimination of all precipitates at the moment of their formation
In the first case once precipitated salt can later react whit solution, producing new solids and the corresponding changes in the composition of the liquid phase. Fractional crystallization, however, follows completely different path because back reaction with previously formed precipitates is not possible.
Whereas equilibrium evaporation is a usual situation, fractional crystallization can hardly be found under natural conditions. Among real systems only solar saltworks, in which seawater is evaporated in a series of pans and where once precipitated salt is really left behind, are similar to this case. Stryctly speaking, howeever, they are somewhere between the cases1 ant 2.
Informationsobtained by following of the seawater evaporation could be important for understanding of the physical chemistry of complex electrolyte solutions, processes that take place during separation of inorganic salts from seawater andformation of evaporites, i.e. rocks composed of minerals precipitated from the seawater as a consequence of evaporation.
