Sažetak
A series of liqiud samples from the Seča solar saltwork was collected and analyzed for the major ions along with Adriatic seawater. The most concentrated saltwork brine was futher evaporated in zhe laboratory. These samples provided a set of solutions ranging from 0.7 to 13.6 ionic strength (in molarity), from which various solid phases precipitated during the evaporation. A Pitzer model for ionic activity coefficients was used to calculate the ion activity products of various phases in these solutions. The complsition of the evaporation brines was controlled by the Ks of gzpsum, anhidryte, halite, epsomite, and possibly astrakhinite over various ionic strength ranges.
